Procedure
A mixture of 1-aminomethylcyclohexyldimethylamine (1.0 g), 4-fluorobenzoyl chloride (2 ml) and pyridine (10 ml) was allowed to stand at room temperature for 1 hr. The crystalline material produced was filtered and recrystallised several times from ethanol/ether to give colourless needles of 1-(4-fluorobenzamidomethyl)-cyclohexyl dimethylamine hydrochloride m.p. 238°-239° .
