N-(3-Formyl-4,5,6,7-tetrahydro-benzo[b]thiophen-2-yl)-2-(3-trifluoromethyl-4,5,6,7-tetrahydroindazol-1-yl)-acetamide (1.30 g, 3.16 mmol) was added portionwise, with stirring, to a solution of sodium borohydride (359 mg, 9.49 mmol) in EtOH (300 mL). The resulting mixture was stirred at RT for 40 min. Acetic acid was added dropwise until the effervescence ceased. The resulting mixture was concentrated in vacuo to afford an off-white solid. The solid was dissolved in diethyl ether (200 mL) and washed with water (100 mL). The organics were dried over sodium sulfate and concentrated in vacuo to yield the title compound as a yellow solid (1.27 g, 3.08 mmol, 97%).
