Definitions
- the present invention relates to a new method for preparing nitroxyalkylesters of the 2 - ( S ) - ( 6 -methoxy- 2 - naphthyl ) -propanoic acid (naproxene) having an enantiomeric excess of the (S) form higher than or equal to 97%, preferably higher than or equal to 98%, combined with high yields, higher than 75-80%, preferably higher than 85%.
- the reaction takes place in the presence of an organic nitrogenated base, such as for example 4 -dimethyl aminopyridine , morpholine, N-methyl morpholine or triethylamine.
- an organic nitrogenated base such as for example 4 -dimethyl aminopyridine , morpholine, N-methyl morpholine or triethylamine.
- An object of the present invention is a process to obtain nitroxyalkylesters of the 2 -( S )-( 6 -methoxy- 2 -naphthyl ) - propanoic acid having an enantiomeric excess higher than or equal to 97%, preferably higher than or equal to 98%, characterized in that an halide of the 2- ( S ) - ( 6 -methoxy- 2 - naphthyl ) -propanoic acid of formula A-Hal, wherein A is the acylic residue of said acid, is reacted in an inert organic solvent with an aliphatic nitroxyalkanol HO-Y-ON0 2 , wherein Y has one of the following meanings: a linear or optionally branched C 1 - C 2 Q I preferably C 2 -C 5 , alkylene; a cycloalkylene with ring from 3 to 8 carbon atoms, preferably from 5 to 7 carbon atoms,
- T being alkylene as above dfeined and p an integer equal to zero or one, alkylene having the above mentioned meaning, nf ' is an integer from 1 to 6 , preferably from 1 to 4; in the presence of an inorganic base, to give the corresponding nitroxyalkylester of the 2- (S) - ( 6 -methoxy- 2 -naphthyl ) -propanoic acid of formula A-0-Y-ON0 2 , wherein A and Y are as above defined.
- Y can also be a combination of two or more of the mentioned group.
- the aliphatic nitroxyalcohol amount on molar basis is in the range 1-2, preferably 1.2-1.5, with respect to that of the acid halide.
- inorganic bases hydroxides, oxides, carbonates and bicarbonates, silicates, aluminosilicates of the alkaline and alkaline -earth metals, or hydroxides, oxides, carbonates and bicarbonates of metals belonging to the group IIB, preferably zinc, or to groups Ilia or IVa , preferably tin, are meant.
- the inorganic base amount is in molar ratio with the acid halide amount generally in the range 1-2, preferably 1.2-1.5.
- aromatic hydrocarbons are meant, such as for example toluene and xylene, chlorinated or fluorinated organic solvents, for example methylene chloride, chlorobenzene , aliphatic esters for example C 1 -C acids esters with C- L -C 8 alcohols such as for example ethyl acetate and butyl acetate, etc.
- the solvent amount is not critical and generally from 1 to 10 volumes of solvent are used, preferabaly from 2 to 5 volumes based on the acid halide weight.
- the reaction is carried out at a temperature in the range -20°C and 50°C, preferably 0°C and 20°C.
- nitroxyalkylesters of the 2 - ( S ) - ( 6 -methoxy- 2 - naphthyl ) -propanoic acid are recovered at the end of the reaction, after addition of water to the organic phase, separation of the phases and solvent evaporation. If necessary, a further purification can be carried out by chromatography on silica gel column in order to increase the product titre.
- the compound can also be purified by crystallization from a suitable solvent.
- Aliphatic nitroxyalcohols can be prepared according to the known methods in the prior art. See for example Gazzetta Chim. It. 1987, 117, 173 and WO 98/25,918.
- Example 2 is repeated using toluene as solvent.
- the nitroxyester yield is 76%, the (HPLC) purity > 99%.
- the enatio eric excess is equal to 98%.
- Example 2 is repeated but using as a base calcium carbonate. 4.6 g, equal to 13.3 mmoles of nitroxyester (yield 90%) are obtained, HPLC purity >99%, enantiomeric excess 98%.
- EXAMPLE 5 is repeated but using as a base calcium carbonate. 4.6 g, equal to 13.3 mmoles of nitroxyester (yield 90%) are obtained, HPLC purity >99%, enantiomeric excess 98%.
- Example 2 is repeated but using as a base calcium alumino- silicate. 4.6 g, equal to 13.3 mmoles of nitroxyester (yield 90%) are obtained, HPLC purity >99%, enantiomeric excess 98%.
- Example 2 is repeated but using as a base triethylamine. The obtained mixture after the reaction is analyzed to evaluate the enantiomeric excess, which results equal to 80%.
- EXAMPLE 8 (comparative)
- Example 2 is repeated but using as a base diisopropylethylamine.
- the mixture obtained after the reaction is analyzed to evaluate the enantiomeric excess, which results equal to 76%.
- EXAMPLE 9 (comparative)
- Example 2 is repeated but using as a base N- methylmorpholine.
- the mixture obtained after the reaction is analyzed to evaluate the enantiomeric excess, which results equal to 56%.
