Procedure

To a solution of {(1S,2S,4R)-2-{[tert-butyl(dimethyl)silyl]oxy}-4-[(2-{[(1S)-5-chloro-3,3-dimethyl-2,3-dihydro-1H-inden-1-yl]amino}pyridin-4-yl)oxy]cyclopentyl}-methanol (28.1 mg, 0.0000543 mol) in DMA (1.00 mL) was added chlorosulfonamide (0.0251 g, 0.000217 mol) in 0.50 ml acetonitrile. The mixture was stirred for 30 min then poured into 50 ml EtOAc and 1.00 ml Et3N. The layers were separated and the organic layer was washed (water) and concentrated. The residue was purified by preparative plate chromatography (85% EtOAc/hexanes) to afford the title compound (28.7 mg, 89%) as a white solid.
