反应详情

A solution of (benzo[d][1,3]dioxol-7-yl)methanol (2 g, 13.14 mmol) and di(1H-imidazol-1-yl)methanone (4.26 g, 26.28 mmol) in 20 mL CH2Cl2 was heated overnight at 50° C. The reaction was quenched with water, extracted with CH2Cl2, dried over Na2SO4, filtered, and concentrated. Purification via silica gel chromatography using 10-70% EtOAc in CH2Cl2 gave (benzo[d][1,3]dioxol-7-yl)methyl 1H-imidazole-1-carboxylate (2.8 g, 86%).
