Reaction Steps

To a solution of isopropylamine (13 mL, 155 mmol) in 60 mL of dichloromethane at 0° C. was added a solution of 5.3 g of 3-methyl-2-nitrobenzenesulfonyl chloride (prepared according to Courtin, A. Helv. Chim. Acta, 1976, 59, 379–387) in 60 mL of dichloromethane dropwise. The reaction mixture was stirred 2 hours at room temperature. Water was added and the layers were separated. The organic layer was dried (sodium sulfate) and the volatiles were removed with a rotary evaporator. The residue was purified by medium pressure liquid chromatography (MPLC), using 20–40% ethyl acetate in hexanes as eluant, to afford 4.3 g of the title compound as a yellow solid.
