Procedure
To a solution of N-(6-((tert-butyldimethylsilyl)oxy)hexyl)cyclohexanamine (246 mg, 0.78 mmol) and triethyl amine (0.22 mL, 1.57 mmol) in methylene chloride (10 mL) at 0° C. was added 2-methylpropane-2-sulfinic chloride (0.13 mL, 1.01 mmol). The mixture was stirred for 2 hours before it was diluted with ethyl acetate and washed with saturated bicarbonate solution and brine. The organic phase was separated and concentrated. Purification on silica gel with ethyl acetate: hexanes from 0:1 to 3:7 provided desired compound, N-(6-((tert-butyldimethylsilyl)oxy)hexyl)-N-cyclohexyl-2-methylpropane-2-sulfinamide, as a clear oil (282.5 mg, 87%). 1H NMR (300 MHz, CDCl3): δ 3.55 (t, J=6.4 Hz, 2H), 3.14 (ddd, J=5.3, 11.7, 14.3 Hz, 1H), 2.94-2.76 (m, 1H), 2.64-2.46 (m, 1H), 2.04-1.92 (m, 2H), 1.84-1.64 (m, 3H), 1.64-1.38 (m, 7H), 1.38-0.94 (m, 6H), 1.14 (s, 9H), 0.85 (s, 9H), 0.05 (s, 6H).
