experiment Scheme 1. Synthesis of Sulfathiazole (Old Method) dry P pyridine -NHCOOH reflux, 25 min a-f-160cm ) + Biothers NH NHCOCH3 NaOH reflux. 50 min fo -NH2 Recovery of the product sulfathiazole 4 from the reaction mixture after alkaline hydrolysis of intermediate 3 posed another practical difficulty. In the original procedure,
