Participants

Reaction Steps

A solution of 4-acetamido-2-bromo-5-phenylthiazole (U.S. Pat. No. 3,244,723) (5.5 g) and sodium acetate (1.55 g) in methanol (110 ml) was hydrogenated at atmospheric pressure over 10% Pd/C catalyst until the theoretical uptake of hydrogen had occurred. The catalyst was removed by filtration and washed with methanol and the filtrate was evaporated to dryness. The residue was recrystallised three times from benzene-petroleum ether (b.p. 60°-80° C.) to give 4-acetamido-5-phenylthiazole (1.5 g) m.p. 105°-7° C. (Found: C, 60.3; H, 4.65; N, 12.7. C11H10N2OS requires: C, 60.5; H, 4.6; N, 12.8%).
