- alcohol for example, methanol, ethanol or isopropanol, preferably methanol, precipitated and worked up by filtration or centrifugation and drying.
- the intermediate ⁇ / - [2- (2-nitrophenyl) ethyl] -1- (phenylmethyl) -4-amino-piperidine can be precipitated and isolated in the form of a salt by adding at least 2 equivalents of an aqueous solution of a strong acid become.
- Suitable acids are hydrochloric, hydrobromic or sulfuric acid, especially hydrochloric acid, to give the dihydrochloride.
- the reaction mixture is cooled to room temperature and treated with an alcohol such as methanol, ethanol or isopropanol, preferably methanol. After addition of an excess of the aqueous acid is heated again to reflux and then cooled again.
- the reaction mixture is made alkaline with an aqueous solution of a base, for example lithium hydroxide, sodium hydroxide, ammonia or potassium hydroxide and, after phase separation, an excess of the aqueous acid is added to the organic phase to crystallize out the desired salt.
- the product can then be worked up by filtration or centrifugation and drying.
- the benzyl protecting group of 3- [1- (phenylmethyl) -4-piperidinyl] -2,3,4,5-tetrahydro-1,3-benzodiazepine-2 (1H) -one is cleaved off.
- the starting material in a polar solvent such as methanol, ethanol, water, acetone, tetrahydrofuran, dimethylformamide or propanol, dissolved, and hydrogenated in a pressure reactor.
- a hydrogenating agent for example, Pd / C or Pd (OH) 2 can be used.
- Advantageous conditions for the hydrogenation are temperatures of 40 to 80 0 C and a hydrogen pressure of at most 3 bar.
- the resulting suspension is cooled to 0 to 5 ° C and stirred to complete the crystallization for a further hour.
- the product is then centrifuged off, washed with a cold mixture of 160 l of water and 9 l of tetrahydrofuran and dried at 45 ° C. while being inertized in a drying oven.
- the remaining solution is hydrogenated in the presence of 860 g Raney nickel at 5O 0 C.
- the catalyst is filtered off and washed with 16 L of methanol.
- the solvent is distilled off and the residue is mixed with 30 L of tetrahydrofuran.
- Half of the tetrahydrofuran used is distilled off and the remaining solution at 2O 0 C added to a suspension of 6.88 kg (42.44 mol, 1.75 eq) of 1, 1-carbonyldiimidazole in 15 L tetrahydrofuran within 1.5 hours. It is stirred for 1 hour at this temperature.
- 20 L of water are added, inoculated and added a further 17 L of water.
- the resulting suspension is cooled to 0 ° C. To complete the Crystallization is stirred for 1.5 hours at 0 ° C. Subsequently, the product is centrifuged off, washed with 30 L of water and dried under inertization in an oven at 45 ° C.
- the catalyst is filtered off and washed with Washed 30 L of methanol.
- the filtrate is concentrated in vacuo and the residue is suspended in 100 L of acetone.
