Reaction Conditions

Reaction Steps

1-Methylguanidine hydrochloride (8.25 g), 4-Fluorobenzaldehyde (4.2 g), ethyl 4-methyl-3-oxo-pentanoate (5.0 g) and DMF (100 ml) were charged to a vessel equipped with a condenser and connected to a nitrogen line. The resultant mixture stirred until a clear solution is obtained. Sodium carbonate (4.0 g) was charged and the mixture heated to 70° C. for 2 hours. The reaction mixture was cooled to ambient temperature, filtered, and the solvents removed by evaporation under reduced pressure. The resultant oil was triturated in water at 50° C. and cooled to give a slurry that was filtered and dried to give ethyl 4-(4-fluorophenyl)-6-isopropyl-2-methylamino-1,6-dihydropyrimidine-5-carboxylate in 63% yield.
