TABLE I a-Chloropropionamidine Hydrochlorides.-These salts were synthesized by the method described previously.2 If the re- action mixture became colored quickly, the reaction was carried out at lower temperature for a shorter period. The procedure for the preparation of one of these salts is described in full, the I \ others being made in similar fashion. The reaction times and ...
