YieldReaction ConditionsOperation in experiment
1.6 M n-Butyl lithium in hexanes (20.2 ml, 32.4 mmol) was added drop wise to a solution of N,N-diisopropylethylamine (5.91 ml, 33.9 mmol) in 25 ml dry THF in ice bath and stirred for 30 minutes. Then tert-butyl methylsulfonylcarbamate in 25 ml dry THF was added slowly and stirred at 0 C. for 1 hour. The mixture was then cooled to -78 C. and 4-phenoxy-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (3.01 g, 15.4 mmol) in 25 ml dry THF was added slowly. The reaction was slowly warmed up to room temperature and stirred at room temperature for 1 hour. Then it was quenched with water, acidified with 1N HCl to pH 3, extracted with ethyl acetate. The combined organic layer was then dried over Na2SO4, filtered and concentrated. Column purification gave 1 g product as off-white solid. 1H NMR (DMSO-d6, 300 MHz) delta ppm 11.34 (s, 1H), 9.39 (s, 1H), 7.54 (d, J=8.10 Hz, 1H), 7.42-7.37 (m, 2H), 7.28 (d, J=2.40, 1H), 7.22-7.12 (m, 2H), 7.03-7.01 (m, 2H), 5.43 (dd, J=9.3, 1.8 Hz, 1H), 4.01 (dd, J=13.5, 2.1 Hz, 1H), 3.54 (dd, J=14.7, 9.3 Hz, 1H), 1.42 (s, 9H).
