Reaction Steps

To isopropyl 2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenylcarbamate (0.298 mmol, 0.10 g) in tetrahydrofuran (1 ml) at room temperature were subsequently added sodium hydride (60% dispersion in mineral oil, 0.350 mmol, 0.014 g) and iodomethane (0.803 mmol, 0.05 ml). After 1 hour aqueous ammonium chloride solution was added and extracted with dichloromethane (three times). The combined organic extracts were dried (sodium sulfate) and concentrated in vacuo to yield isopropyl 2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl(methyl)carbamate (0.14 g) which was used without further purification.
