Procedure: A mixture of N-methylpivalamide (6.2 g) in benzene (50 ml), 4-(2-aminobenzyl)morpholine (9 g) in benzene (40 ml) and phosphorus oxychloride (5 ml) was heated at 80°-85° C. for 12 hours to yield a solid which was dissolved in methanol (25 ml) and treated with fumaric acid (1.4 g) to give N-methyl-N'-(2-morpholinomethylphenyl)pivalamidine monofumarate (m.p. 167°-168° C.) which was recrystallised from propan-2-ol. to yield a solid which

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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. the mixture heated at 65°-70° C. for four days
