Definitions
- the present invention relates to a novel process for the preparation of S(+) 2-ethoxy-4-[N- ⁇ l-(2-piperidinophelyl)-3- methyl-1- butyl aminocarbonylmethyl]-benzoic acid derivatives.
- EP 0 207 331 claims two polymorphous forms B and C of 2- ethoxy-4-[N- ⁇ l-(2-piperidinophelyl)-3- methyl-1-butyl aminocarbonylmethyl]-benzoic acid having the Formula IV and process for preparation thereof.
- EP 0 589 874 claims S(+) 2-ethoxy-4-[N- ⁇ l-(2-piperidinophelyl)- 3- methyl- 1-butyl aminocarbonylmethyl]-benzoic acid having the Formula IV and process for preparation thereof.
- the compound of formula (IV) is from a new class of hypoglycemic benzoic acid derivatives for the treatment of non-insulin dependent diabetes mellitus (NIDDM).
- NIDDM non-insulin dependent diabetes mellitus
- reaction of the amine of Formula II with a carboxylic acid of Formula III is carried out in the presence of N,N'-carbonyldimidazole, N,N'dicyclohexylcarbodiimide or triphenylphosphine/carbon tetrachloride and triethylamine.
- WO 2003/027072 claims process for preparation of compound of formula I by reacting an S(+) amine compound of formula II with a carboxylic acid of formula III in the presence of pivaloyl chloride and a base.
- the reagents used here suffer from disadvantages like probable racemisation, expensiveness, additional reagents e.g. a base, low yields of the product, extra purification steps to obtain final product, repeated crystallization, hazardous and industrially impossible.
- the present invention provides a process for the preparation of compound of formula I comprising, reacting the (S) amine of Formula II
- the novel process employed in the instant invention has following definite advantages: a) Remarkably low risk of allergization compared to other reagents like DCC. b) Low toxicity of Propane phosphonic anhydride and its reaction products. c) Low racemization of products during reaction. d) By products are water soluble leading to simple work up and easy isolation of product. e) Reaction proceeds under ambient conditions. f) High yields.
- the present invention provides a process for the preparation of compound of formula I comprising, reacting the (S) amine of Formula II
- the protecting group P in the compound of Formula III is any carboxylic acid protecting group which can be easily removed, like ester groups.
- the reaction may be carried out in any suitable solvent such as ethyl acetate, dichloromethane etc.
- the reaction is carried out at temperatures of between -25°C and
