実験手順

(S)-(1-((2-amino-2,3-dihydro-1H-inden-5-yl)methyl)-3-(trifluoromethyl)-1H-pyrazol-4-yl)methanol (0.064 mmol, 20 mg) was dissolved in tetrahydrofuran (1 mL) and triethylamine (0.128 mmol, 17.8 μL) followed by 2-chlorobenzenesulfonyl chloride (0.064 mmol, 13.6 mg) and the solution stirred at room temperature overnight. The reaction was concentrated to dryness to give a brown residue which was dissolved in DMSO (1 mL) and purified on preparative basic HPLC to give the title compound (17.4 mg, 0.036 mmol, 56.0%) MS (ESI): m/z [M−H]− 484.5.
