Procedure
A cooled (0° C.) solution of methyl 2,4-dichloropyrimidine-6-carboxylate (Apollo, OR2558, 25.00 g; 120 mmol) in THF (500 mL) was treated with a solution of n-methylcyclohexylamine (Aldrich, 15.7 ml; 121 mmol) and triethylamine (18.4 ml; 133 mmol) in THF (250 mL). The reaction mixture was stirred for 16 hours at RT. Water (250 mL) was poured into the reaction mixture which was extracted with EtOAc. The combined organic extracts were dried over magnesium sulfate, filtered and concentrated to obtain the crude product, which was purified by recrystallisation from MTBE. The title product was obtained as a beige solid (25.7 g, 75%).
