Reaction Steps

2-(2-(4-Formyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)acetamido)-N-(2-hydroxyethyl)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (30 mg, 0.068 mmol), 2,2,2-trifluoroethylamine (19.8 mg, 0.20 mmol) and DCM (1 mL) were treated with acetic acid (5 drops) and sodium triacetoxyborohydride (58 mg, 0.272 mmol) and the mixture stirred at RT overnight. The sample was concentrated and re-dissolved in dimethylsulfoxide (1 mL), filtered and purified by preparative LCMS followed by additional purification by SCX ion exchange chromatography to yield the title compound (10 mg, 0.02 mmol, 29%).
