Participants

Reaction Steps

Ethyl 4-(2-chloro-4-methylsulphenylbenzoyl]-5-cyclopropylisoxazole-3-carboxylate (2.4 g) was added to a stirred solution of sodium hydroxide (2.2 g) in ethanol and water while maintaining the temperature below 0° C. The mixture was stirred at below 0° C. for 2 hours. The mixture was carefully acidified to pH1 at 0° C. and the solid was filtered off and dried to give 4-(2-chloro-4-methylsulphenylbenzoyl)-5-cyclopropylisoxazole-3-carboxylic acid (2.1 g) as an off-white solid, m.p. 106°-108° C. (decomposition).
