Reaction Steps

A mixture of 2-methyl-1-(2-morpholinophenyl)-3-methyl-2-thiopseudourea (4 g prepared from the hydroiodide salt described in Example 210), potassium hydroxide (1.7 g), n-pentylamine (2.1 g), lead acetate trihydrate (5.8 g) and ethanol (20 ml) were heated at 90°-95° C. for 40 minutes to yield an oil which was extracted with hexane to give 1-methyl-2-(2-morpholinophenyl)-3-(n-pentyl)guanidine which was converted into its monofumarate salt (m.p. 148°-149° C.) which was recrystallised from a 3:5 mixture of methanol and ether.
