Procedure

A mixture of the amine from example 4 (200 mg, 0.53 mmol), 2-chloropyrimidine (66 mg, 0.58 mmol) and potassium carbonate (72 mg, 0.53 mmol) in N,N-dimethylformamide (5 ml) was stirred at room temperature for 18 hours. TLC analysis showed starting materials remained, so additional 2-chloropyrimidine (66 mg, 0.58 mmol) was added, and the reaction was stirred at 80° C. for a further 72 hours. The cooled mixture was evaporated under reduced pressure, the residue was partitioned between ethyl acetate and brine, and the layers were separated. The organic layer was washed with water, wash with ammonium chloride solution, dried over magnesium sulphate and then evaporated under reduced pressure. The residual yellow oil was purified by column chromatography on silica gel using dichloromethane:methanol (95:5) as eluant, to afford the title compound as a yellow oil (117 mg).
