21.5 g of O-(1-diphenylmethoxycarbonyl-1-methylethyl)hydroxylamine and 12 g of (2-amino-4-thiazolyl)glyoxylic acid are refluxed for 3 hours in 1500 ml of methanol. The cloudy reaction mixture is filtered whilst hot, and then stirred for 12 hours at 10°. The resultant crystalline deposit is filtered off by suction and washed with methanol. 24 g (80%) of the title compound are obtained.
