Reaction Conditions

Reaction Steps

A mixture of 2-methyl-1-(2-morpholinophenyl)-3-methyl-2-thiopseudourea hydriodide (7.86 g prepared as described in Example 210), cyclopentylamine (2.9 g), anhydrous sodium carbonate (6.36 g) and ethanol (100 ml) was heated in a stainless steel pressure vessel in an oil bath at 110° C. for 24 hours. The reaction mixture was cooled, filtered and the solvent was partially removed. The residue was poured into ice and the resulting mixture extracted with dichloromethane. The extract was dried, filtered and the solvent removed to give a residue which was treated with fumaric acid to give 1-cyclopentyl-2-(2-morpholinophenyl)-3-methylguanidine monofumarate (m.p. 220° C.) which was recrystallised from a 1:1 mixture of methanol and ether.
