To a solution of [(3aR,4R,6R,6aS)-6-({6-[(1S)-2,3-dihydro-1H-inden-1-ylamino]pyrimidin-4-yl}amino)-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl]-methanol (100. mg, 0.252 mmol) and Et3N (0.0527 mL, 0.378 mmol) in DCM (2.50 mL) was added dropwise a 2.00 M solution of chlorosulfonamide in ACN (0.190 mL, 0.380 mmol) at 0° C. and the mixture was stirred for 2 h. The reaction was diluted with DCM, quenched with H2O and the organic layer was separated, then concentrated in vacuo. The residue was purified via silica gel chromatography eluting with a gradient of 0 to 10% MeOH in DCM to afford the title compound (65.0 mg, 54%). LC/MS: Rt=1.58 min, ES+ 476 (AA standard).
