Originator
Opren,Dista Lilly,UK,1980
Uses
A non-steroidal anti-inflammatory ophthalmic agent.
Definition
ChEBI: A monocarboxylic acid that is propionic acid substituted at position 2 by a 2-(4-chlorophenyl)-1,3-benzoxazol-5-yl group. It was used as a non-steroidal anti-inflammatory drug until 1982 when it was withdrawn from the market due to adverse side-effects inc uding liver necrosis, photosensitivity, and carcinogenicity in animals.
Manufacturing Process
The 6-benzoxazolyl analog of the 5-benzoxazolyl product is prepared as
follows:
(a) Ethyl 2-(2-p-chlorophenyl-6-benzoxazolyl)propionate: A solution of ethyl
2-(3-hydroxy-4-aminophenyl)propionate (2.5 g) in pyridine (15 ml) was
treated with p-chlorobenzoyl chloride (1.65 ml) at 5°C. After stirring for 2
hours at room temperature the solution was evaporated to dryness.
The residue was heated at 220°C until no more water was evolved, then was
allowed to cool. This yielded ethyl 2-(2-p-Chlorophenyl-6-
benzoxazolyl)propionate.
(b) 2-(2-p-Chlorophenyl-6-benzoxazolyl)propionic acid: A solution of ethyl 2-
(2-chlorophenyl-6-benzoxazolyl)propionate (4 g) in aqueous sodium hydroxide
(30 ml) was heated on a steam bath for one-half hour. On cooling the black
solution was washed with chloroform. On acidification of the black solution
with hydrochloric acid the mixture was extracted with chloroform. This
solution on evaporation yielded 2-(2-p-chlorophenyl-6-benzoxazolyl)propionic
acid, MP 196°C.
