Procedure

To a solution of the title F compound (4′-trifluoromethylbiphenyl-2-carboxylic acid (2-amino-indan-5-yl)-amide, 0.100 g, 0.250 mmol) in methylene chloride (10 mL) is added diisopropylethyl amine (0.036 g, 0.280 mmol) followed by benzenesulfonyl chloride (0.046 g, 0.260 mmol). After 1 h, the reaction mixture is poured into ethyl acetate and washed with 1 N HCl, 8% NaHCO3 solution, water, and brine. The organic layer is dried (MgSO4) and concentrated under reduced pressure to give an oil which is purified by silica gel chromatography. Drying under vacuum at 60° C. gives 4′-trifluoromethyl-biphenyl-2-carboxylic acid (2-benzenesulfonylamino-indan-5-yl)-amide as a non-crystalline solid; mp 96° C. sinters. MS (ES+), m/z 537 (M+1), 554 (M+NH4+).
