Procedure

Tert-butyl amine [8.5 g, 12.32 ml, 116.0 mmol) was added dropwise to a stirred suspension of 4-bromo-5,6,7,8-tetrahydronaphthalene-1-sulfonyl chloride (59a, 12.0 g, 38.8 mmol) in 150 ml tetrahydrofuran at 0° C. The reaction mixture was then stirred at a temperature of about 25° C. for 2 hours. The progress of the reaction was monitored by TLC. Water (100 ml) was added to the reaction mixture, and the mixture so obtained was extracted with ethyl acetate (2×150 ml). The combined organic layer was then dried over sodium sulphate, and the dried organic layer was concentrated under reduced pressure to obtain a crude product, which was then purified by column chromatography over silica gel (100-200 mesh) using 15% ethyl acetate in hexanes as an eluent to obtain the title compound (2.34 g, 17.4%).
