Reaction Steps
Another sample of 2,5-diphenylthiazole is prepared by reacting alpha-(benzamido) acetophenone with phosphorus pentasulfide according to the procedure given by Gabriel, Berichte 43, 137 (1910); C.A. 4, 928. The overall yield, based on phenacyl bromide, is about 25% and the product melts at 103°-106° C.
