Reaction Steps

To a solution of (R)-1-(2-aminopyrimidin-4-yl)ethanol (6a) (250 mg) in dry N-methylmorpholine (4 mL) at ambient temperature was added potassium 2-methylpropan-2-olate (222 mg) and the solution was left to stir for 30 min then 2-fluoro-3-(trifluoromethyl)pyridine (282 mg) was added the mixture was stirred for 10 min at ambient temperature and then heated to 100° C. with microwave irradiation for 2 minutes then cooled and quenched into water (50 mL). The precipitated solid was filtered and washed with water and air dried under a slight vacuum. The semi-dried material was taken up in methylene chloride and dried over magnesium sulfate to which activated charcoal was added then filtered through a bed of dicalite and evaporated to give the title compound (359 mg), MS (ES): m/z 285 [M+H]+.
