Definitions
- the invention relates to a process for the preparation of 2- [5- (4-fluorophenyl) -3-pyridylmethylaminomethyl] -chroman of the formula I,
- 5-HT 1A receptor agonists are therefore for use in the manufacture of a medicament for the prophylaxis and / or treatment of secondary diseases after cerebral infarction (apoplexia cerebri), for example stroke and cerebral ischemia, for the prophylaxis and control of cerebral diseases, for example migraine
- apoplexia cerebri for example stroke and cerebral ischemia
- cerebral diseases for example migraine
- the object of the present invention was therefore to find a new and effective synthesis variant for the compounds described above.
- the invention therefore relates to a process for the preparation of 2- [5- (4-fluorophenyl) -3-pyridylmethylaminomethyl] -chroman of the formula I,
- the invention therefore relates to the process as described above, characterized in that the reactive form of the 2-aminomethyl-chroman is prepared in situ from a salt of the 2-aminomethyl-chroman.
- Particularly suitable salts of 2-aminomethyl chroman are 2-
- Diastereomers are preferably formed from the racemic mixture by reaction with an optically active release agent.
- Suitable release agents are e.g. optically active acids, such as the D and L forms of tartaric acid, diacetyl tartaric acid, dibenzoyl tartaric acid, mandelic acid, malic acid, lactic acid or amino acids or the various optically active camphorsulfonic acids such as ß-camphorsulfonic acid.
- the preparation can be carried out, for example, starting from the commercially available chroman-2-carboxylic acid by the following reactions:
- the invention also relates to a process for the preparation of (R) - (-) - 2- [5- (4-fluorophenyl) -3-pyridylmethylaminomethyl] -chroman of the formula Ia,
- the (R) -2-aminomethylchroman can also be prepared by reacting racemic 2-aminomethylchroman with (S) -N-tosylproline and then resolving the racemate by crystallization.
- the solubilities of the two diastereomeric salts of racemic amine with enantiomerically pure N-tosyl- (S) -proline are so different that the pure (R) / (S) -diastereomer of the formula III can be obtained by normal crystallization.
- the result is (R) -2-aminomethyl-chroman N- (tosylsulfonyl) - (S) -prolinate of the formula III
- the invention also relates to the diastereomeric salt (R) -2-aminomethylchroman N- (toluenesulfonyl) - (S) -prolinate.
- Figure 2 (Fig. 2): X-ray structure analysis of (R) -2-aminomethylchroman N- (toluenesulfonyl) - (S) -prolinate.
- 5- (4-fluorophenyl) pyridine-3-carbaldehyde can be prepared according to known
- borohydrides are lithium borohydride, sodium borohydride, sodium cyanoborohydride, potassium borohydride or borohydride on polymeric carrier materials, for example Amberlyst A-26 BH 4 " form. Particular preference is given to using sodium borohydride which has previously been reacted with methanol to form sodium trimethoxyborohydride.
- Any solvent is suitable for the reaction in the presence of borohydrides, provided it does not interfere with the starting materials.
- Protic solvents for example alcohols such as ethanol or methanol or mixtures thereof, are particularly suitable.
- Suitable reaction temperatures are between 0 ° and 70 °, preferably between 10 and 50 °, particularly preferably between 20 and 35 ° C.
- Suitable hydrogenation catalysts are, for example, metals from the eighth subgroup, for example Raney nickel, palladium or platinum.
- Palladium or platinum catalysts can be present on a support material, for example on activated carbon, calcium carbonate, barium sulfate or strontium carbonate, in the form of their oxides, for example platinum oxide or in finely divided form. Is preferably carried out at a pressure of 1 to 200 bar and at temperatures between -80 ° and + 150 ° C, particularly preferably at room temperature and normal pressure.
- the base of formula I obtained can be converted into the associated acid addition salt using an acid.
- Acids which provide physiologically acceptable salts are suitable for this reaction.
- So inorganic acids can be used, e.g. Sulfuric acid, hydrohalic acids such as hydrochloric acid or hydrobromic acid, phosphoric acids such as orthophosphoric acid, nitric acid, sulfamic acid, furthermore organic acids, in particular aliphatic, alicyclic, araliphatic, aromatic or heterocyclic mono- or polybasic carboxylic, sulfonic or sulfuric acids, such as formic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, acetic acid, Propionic acid, pivalic acid, diethyl
- the salt formation in ethanol takes place by precipitation with hydrochloric acid (37%).
- the result is 2- [5- (4-fluorophenyl) -3-pyridylmethylaminomethylj-chroman dihydrochloride hemihydrate, (R) - (-) - 2- [5- (4-fluorophenyl) -3-pyridylmethylaminomethyl] -chroman dihydrochloride hemihydrate or (S) - (+) - 2- [5- (4-fluorophenyl) -3-pyridylmethylaminomethyl] chroman dihydrochloride hemihydrate.
- the invention relates to the process as described above, characterized in that (R) - (-) - 2- [5- (4-fluorophenyl) -3-pyridylmethylaminomethylj-chroman dihydrochloride or (S) - (+) - 2 - [5- (4-fluorophenyl) -3-pyridylmethylaminomethyl] -chroman dihydrochloride is prepared.
