Procedure

A stirred mixture of 5.3 g of (4,6-dichloro-2-pyrimidinylthio)acetic acid ethyl ester, 3.4 g of 4-aminobiphenyl and 2.1 g of sodium carbonate in 100 ml. of ethanol was heated under reflux for 5 hr. The reaction mixture was filtered and water was added to the filtrate to initiate precipitation. The precipitate was recrystallized from ethanol to give 3.1 g of product, mp. 110°-112°C..
