Reaction Steps

3.38 g of 2-[4 (2,3-dichlorophenylcarbamoyl)-phenyl]-propionic acid was dissolved in 30 ml of anhydrous tetrahydrofuran. While cooling the solution with ice water, 2.43 g of N,N'-carbonyldiimidazole was added thereto, and the mixture was stirred for 30 minutes. Thereafter, 0.74 g of isobutyl alcohol was added thereto. The mixture was returned to room temperature and stirred for 5 hours. After completion of the reaction, the reaction solution was poured into 300 ml of water, and the resulting crystals were collected by filtration, washed with water and dried, and then recrystallized from toluene-hexane to obtain 3.15 g of desired isobutyl 2-[4-(2,3-dichloropheylcarbamoyl)-phenyl]-propionate. The yield was 80%, and the melting point of this compound was from 70° to 72° C.
