Reaction Steps

A mixture of 2-methyl-1-(2-piperidino)phenyl]-2-thiopseudourea hydroiodide (7.5 g prepared as described in Preparative Procedure G), 2-methoxyethylamine (2 ml) and ethanol (40 ml was stirred at ambient temperature for 20 days. Removal of the solvent gave a residue which was dissolved in methanol and treated with fumaric acid to give 1-(2-methoxyethyl)-2-(2-piperidinophenyl)guanidine hemifumarate (m.p. 218°-220° C.) which was recrystallised from a 1:2 mixture of methanol and ether.
