Participants

Reaction Steps

To trans-tert-butyl-4-(hydroxymethyl)cyclohexylcarbamate (8.0 g, 34.9 mmol) in DCM (180 mL) and DMSO (60 mL) at 0° C. is added DIPEA (24.37 mL, 140 mmol) and pyridine sulfur trioxide (22.21 g, 140 mmol) dissolved in DMSO (60 mL). The mixture is stirred at room temperature for 15 minutes and then is partitioned between 1M HCl and diethylether. The organic phase is separated and washed with 1M HCl, water then saturated brine. The mixture is dried (MgSO4) and solvent evaporated to give the expected product; [MH+MeCN]+269.
