Procedure

A mixture of methyl 9-chloro-1-(2,4-dichloro-6-methylphenyl)-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazole-6-carboxylate (1.00 g, 2.35 mmol), formamide (0.937 mL, 2.35 mmol) and sodium methoxide (28% solution in methanol, 2.4 mL) in N,N-dimethylformamide (6 mL) was stirred at 120° C. for 14 hr. The mixture was diluted with aqueous saturated ammonium chloride. The resultant precipitate was collected by filtration, washed with water and diisopropyl ether to give the title compound as a colorless solid.
