To a solution of 4,6-dichloropyrimidine-5-carbaldehyde (1.00 g, 5.65 mmol) in chloroform at 0° C. were added azetidine (99%, 0.392 mL, 5.71 mmol) and triethylamine (5 drops). The reaction mixture was allowed to warm to room temperature and then stirred for 18 hours. The reaction mixture was filtered, and the filtrate was purified by silica gel chromatography (Gradient: 0% to 100% ethyl acetate in heptane) to provide the product. Yield: 880 mg, 4.45 mmol, 79%. LCMS m/z 198.1, 200.1 (M+1). 1H NMR (400 MHz, CD3OD) δ 2.34-2.43 (m, 2H), 4.12-4.33 (br m, 4H), 8.30 (s, 1H), 10.28 (s, 1H).
