Procedure

To benzimidoylaminoacetic acid hydrochloride (2.2 g., 10 m moles) in 40 ml. of dry methylene chloride is added 2.5 g. (12 m moles) of phosphorous pentachloride, and the reaction mixture allowed to stir overnight at room temperature. The product is filtered, washed successively with methylene chloride (50 ml.), chloroform 2× 75 ml.) and hexane (50 ml.) and dried in vacuo, 2.5 g. (99% yield).
