실험 절차

A round-bottom-flask containing 5-fluoropyrimidine-2-carbonitrile (Method 6, 1.50 g, 12.19 mmol) was charged with anhydrous THF (30 ml) under N2. The solution was cooled to 0° C., and a solution of MeMgBr (4.90 ml of a 3.0 M solution in ether, 14.62 mmol) was added dropwise. After 2 hours at 0° C., the reaction mixture was quenched with ice water and extracted with EtOAc. The organic extract was washed with brine, dried over Na2SO4, and evaporated to dryness to give the title compound as an oil (0.778 g, yield 46%). GC-MS, 140 (M); 1H NMR (CDCl3) δ 8.65 (s, 2H), 2.65 (s, 2H).
