Hydrolysis of N, N-Dimethyl-N'-benzoylformamidinium Chloride.-To 15 ml. of water was added 4.0 g. of the formamidinium chloride. After a few minutes, a white crystalline precipitate formed. The yield of N-formylbenzamide was 2.8 g.(99%), mp 107-108". Authentic N-formylberizamide was prepared by the method of Thompson, 5 mp 106-1OX". The infrared spectrum was identical with the product obtained from the hydrolysis of N, N- ...
