Participants

Reaction Steps

A solution of 4-tert-butylbenzoyl chloride (5.24 g; 26.7 mmol) in dichloromethane (40 mL) was added portionwise to a solution of 2-methyl-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenylamine (4) (6.22 g; 26.7 mmol) and triethylamine (5.6 mL; 40.1 mmol) in dichloromethane (60 mL) and the mixture was stirred at room temperature for 16 hr. Water (100 mL) was added and the mixture extracted with dichloromethane (3×70 mL). The combined organic layers were washed with water (2×100 mL) and brine (1×100 mL), dried over magnesium sulfate and evaporated under reduced pressure to give 4-tert-butyl-N-[2-methyl-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-benzamide (5) as a white solid (9.7 g).
