Ethyl 5-bromo-3-(1,1-dioxidotetrahydro-2H-thiopyran-3-yl)-1H-indole-7-carboxylate (0.380 g, 0.949 mmol), was stirred in a methanol (5 mL)/water (3 mL) solution. 6M NaOH (1.5 mL, 0.900 mol, 10 eq) was added and the reaction was heated to 85° C. for 1.5 hours. The methanol was concentrated and the aqueous solution was acidified with 6M HCl. The resulting white solid was filtered and dried under vacuum to give 0.325 g (92%) of the title compound.
