Reaction Steps

[2-({2-[2-(3-Trifluoromethyl-4,5,6,7-tetrahydroindazol-1-yl)-acetylamino]-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carbonyl}-amino)-ethyl]-carbamic acid tert-butyl ester was dissolved in a solution of DCM (1 mL) and TFA (1 mL) and stirred at RT for 1 h, before concentration in vacuo. The resulting colourless oil was redissolved in DCM (1 mL) and triethylamine (7.70 μL, 0.055 mmol) added, followed by methanesulfonyl chloride (2.20 μL, 0.028 mmol). The resulting mixture was stirred at RT overnight. The sample was concentrated in vacuo and the residue obtained purified by preparative reverse phase HPLC to yield the title compound as a white solid (4 mg, 0.007 mmol, 25%).
