24.7 g (171 mmol) of 5-methylfuran-3-carbonyl chloride were added dropwise to a stirred mixture of 80 ml of a 25% strength ammonium hydroxide solution and 80 ml of benzene at 25-40° C. The resulting mixture was stirred for 3 h and left to stand overnight. The next day, white crystals of the amide were filtered off, washed with cold water and dried to constant weight at 40-45° C. Yield 19.7 g (158 mmol, 92%), melting point 158° C.
