反応手順
To 2-amino-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (120 mg) in dry DCM (3 ml) and triethylamine (1.5 equiv., 114 uL) was added acetic anhydride (1.1 equiv., 57ul) and the reaction mixture was stirred at room temperature overnight. Dichloromethane/brine extraction and purification on silica gave 66 mg of N-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine-2-yl]-acetamide.
