Procedure
To a solution of the compound obtained in step C (31 mg, 0.1 mmol) in dry pyridine (1.0 mL) is added ethanesulfonyl chloride (14 μL, 0.15 mmol). The mixture is stirred at room temperature overnight and diluted with water (5 mL). The organic is extracted with DCM (5 mL) and washed with HCl (2N, 2×3 mL), water (2×4 mL) and brine (3 mL) and chromatographed (silica gel, EtOAc/DCM, 0.5/9.5) to provide the product, ethanesulfonic acid [4-(3-cyano-1-ethyl-6-trifluoromethoxyindol-2-yl)phenyl]amide (33 mg, 83%).
