Reaction Steps

4-Chloro-2,6-dimethylfuro[2,3-d]pyrimidine (M).To a 50 mL flask was added 1.64 g (1 mmol) L and 10 mL POCl3. The resulting mixture was refluxed for 2 h, and the solvent was removed under reduced pressure to afford a dark residue. To this was added 30 mL of CHCl3 and 3 g of silica gel. The solvent was evaporated to afford a plug. Column chromatography of the plug with hexane:acetyl acetate=20:1 as eluent afford 1.55 g (85%) M as a yellow solid; Rf 0.26 (Hexane/EtOAC 15:1); 1H NMR (DMSO-d6) δ 2.48 (s, 3 H), 2.63 (s, 3 H), 6.77 (s, 1 H).
