Procedure

(S)-(1-((2-amino-2,3-dihydro-1H-inden-5-yl)methyl)-3-(trifluoromethyl)-1H-pyrazol-4-yl)methanol (0.08 mmol, 25 mg) was dissolved in THF (1 mL) and triethylamine (0.25 mmol, 35 μL, 25 mg) followed by furan-2-sulfonyl chloride (0.084 mmol, 14.05 mg) and the solution stirred at room temperature overnight. The reaction was concentrated before partitioning between dichlormethane (3 mL) and 1N HCl (3 mL). The organic layer was collected and dried using a hydrophobic frit and concentrated under a stream of nitrogen to give a brown residue which was dissolved in DMSO (1 mL) and purified on preparative basic HPLC to give (S)—N-(5-((4-(hydroxymethyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl)methyl)-2,3-dihydro-1H-inden-2-yl)furan-2-sulfonamide (14.3 mg, 0.032 mmol, 40.5%) MS (ESI): m/z [M+H]+ 442.2
