Procedure
A solution of 7.8 g. (0.047 mole) of β-carbomethoxypropionamidine hydrochloride in 217 ml. of 12N hydrochloric acid is heated at steam bath temperatures for 1 hour. The solution is cooled, evaporated in vacuo to dryness, and the residual product triturated several times with ethylene dichloride and filtered, 7.1 g. (99% yield), m.p. 138°-140° C. (McElvain, et al., J. Am. Chem. Soc., 71,40 (1949) reports a melting point for crude product of 131°-137° C.).
