Reaction Steps

A mixture of N-methylpivalamide (11.5 g) in benzene (120 ml) and phosphorus oxychloride (9.2 ml) was stirred at room temperature for 3 days. A solution of 1-(2-aminophenyl)piperidine (14 g) in benzene (80 ml) was added and the mixture heated at 65°-70° C. for four days to give N-methyl-N'-(2-piperidinophenyl)pivalamidine (m.p. 78° C.) which was recrystallised from hexane. The product was obtained as a 0.25 hydrate.
