2,4-Dichloro-6-phenylfuro[3,2-d]pyrimidine 43 (165 mg, 1.0 eq) was suspended in methanol (4.2 ml) and treated with morpholine (0.22 ml, 4.0 eq). Reaction mixture was stirred at room temperature for 4 h. Solid was filtered to yield pure 2-chloro-4-morpholino-6-phenylfuro[3,2-d]pyrimidine 44 (163 mg, 83% yield) as a beige solid: 1H NMR (CDCl3, 400 MHz) δ 7.80 (m, 2H), 7.51 (m, 3H), 6.99 (m, 1H), 4.10 (m, 4H), 3.89 (m, 1H); MS (Q1) 316 (M)+.
