Reaction Steps

A mixture consisting of 6.0 gm (0.0202 mol) of 2-methylmercapto-4-(2',6'-dichloro-phenyl)-2-imidazoline hydrochloride and 3.25 gm (0.025 mol) of N-(β-amino-ethyl)-morpholine was melted by heating it for 30 minutes at 150° C. Thereafter, while still hot, the molten mass was dissolved in ethanol and reprecipitated from solution by addition of ether. The precipitate, which solidified after some time, was collected and recrystallized from ethanol/acetone and, for further purification, briefly heated in boiling water in the presence of activated charcoal. The mixture was filtered, the filtrate was evaporated to dryness, and the residue was washed with acetone, yielding 3.0 gm (41.8% of theory) of the white crystalline compound of the formula ##STR11## which had a melting point of 225° C.
