90% | With phosphorus(V) oxybromide In N,N-dimethyl-formamide at 110℃; for 1 h; | 4-hydroxy-6-methylpyridin-2(1H)-one (500 mg, 4.00 mmol) was mixed with phosphoryl bromide (881 mg, 3.07 mmol) and DMF (1.8 mL) was added. The reaction mixture was heated at 110 oC. After 5 min, more DMF (1.8 mL) was added and the reaction was heated at 110 oC for 1 h. The reaction was cooled down and ice cold water was carefully added, followed by solid sodium bicarbonate until pH reached 7. The precipitate was filtered, rinced with cold water and let dry under air to give the title compound (520 mg, 2.77 mmol, 90percent). |

30% | With di-isopropyl azodicarboxylate; triphenylphosphine In tetrahydrofuran at 20℃; for 18 h; | Diisopropyl diazocarboxylate (323 mg, 1.60 mmol) was added to a solution of 4- bromo-6-methylpyridin-2-ol (200 mg, 1.06 mmol), methanol (54 ^L, 1.3 mmol) and triphenylphosphine (419 mg, 1.60 mmol) in THF (4.6 mL). The reaction mixture was stirred at r.t. for 18 h. Ethyl acetate was added and the mixture was washed with 1N NaOH (3x). The organic layer was dried with sodium sulfate, filtered and evaporated under reduced pressure. The crude product was purified by flash chromatography on silica gel using a solution of ethyl acetate in hexanes (5 to 10percent) to give the title compound (65 mg, 0.32 mmol, 30percent). |
