1-(异氰基(甲苯磺酰)甲基)-2-甲氧基苯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a soln. of 1,4-dioxane-2,5-diol (120 mg, 0.995 mmol) in THF (8 ml) was added methylamine (2.8 ml, 0.664 mmol) at r.t. The resulting mixture was stirred at r.t for 75 min. Then 1-(isocyano(tosyl)methyl)-2-methoxybenzene (200 mg, 0.664 mmol) was added while keeping reaction mixture at <30° C. by a water bath. The reaction mixture was stirred at r.t overnight. Evaporated to leave white solid, dissolved in DMF, and purified by Pre-HPLC to afford (4-(2-methoxyphenyl)-1-methyl-1H-imidazol-5-yl)methanol (84 mg, 0.377 mmol, 38.6% yield) as a colorless oil. 1H-NMR (MeOD), δ: 8.97 (1H, s), 7.55 (1H, t, J=7.5 Hz), 7.47 (1H, d, J=8.0 Hz), 7.22 (1H, d, 8.0 Hz), 7.15 (1H, t, J=7.5 Hz), 4.67 (2H, s), 4.05 (3H, s), 3.89 (3H, s). reaction mixture at <30° C. by a water bath The reaction mixture was stirred at r.t overnight Evaporated to leave white solid purified by Pre-HPLC
