Reaction Steps
60% Sodium hydride (0.55 g) and methyl iodide (1.2 mL) were added to a DMF (6.0 mL) solution of t-butyl(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)carbamate (2.0 g), and the mixture was stirred for 18 hours at room temperature. Ethyl acetate and water were added to the reaction mixture, and the organic layer was isolated. The extract was washed sequentially with water and brine, and dried over anhydrous sodium sulfate. Then, the desiccant was filtered out, whereafter the solvent was distilled off under reduced pressure. Hexane was added to the residue, and the precipitated solid was collected by filtration to obtain t-butyl=methyl(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)carbamate (white solid) (1.46 g, 70%).
