Reaction Steps

A mixture of (R)-(+)-1-(2-napthyl)ethylamine (102.6 mg, 0.599 mmol), 2,4-dichloro-5-fluoro pyrimidine (100 mg, 0.599 mmol) and cesium carbonate (390 mg, 1.2 mmol) was dissolved in 1,4-dioxane (3 ml) and H2O (3 ml) in a 10 ml microwave vial. The mixture was stirred in the microwave reactor at 80° C. for 10 minutes. The residue was dissolved in CH2Cl2 (50 ml), washed with water (20 ml), brine (20 ml) dried (Na2SO4) and concentrated to get the crude intermediate 2-chloro-5-fluoro-pyrimidin-4-yl)-(1-naphthalen-2-yl-ethyl)-amine.
