Reaction Steps
To a solution of ((1S,3S)-3-{[8-(1-naphthyl)-9H-purin-6-yl]oxy}cyclopentyl)-methanol (66.1 mg, 0.000183 mol) in DMA (8.12 mL) at 0° C. was added chlorosulfonamide (106 mg, 0.000917 mol) in CH3CN (2.0 mL). The reaction was stirred at 0° C. for 10 mins, then 23° C. for 3 hours. The reaction was quenched with water and extracted with EtOAc (3×). The combined organics were washed with water (2×), dried (Na2SO4), filtered, and concentrated. The residue was purified by flash chromatography (0 to 6% MeOH/CH2Cl2) to obtain 56.3 mg (70%) of the title compound as a white solid. 1H NMR (CD3OD, 400 MHz) δ: 8.52-8.48 (m, 2H), 8.10-8.07 (m, 1H), 8.01-7.98 (m, 1H), 7.90-7.87 (m, 1H), 7.65-7.57 (m, 3H), 5.89-5.85 (m, 1H), 4.12-4.07 (m, 2H), 2.75-2.66 (m, 1H), 2.30-2.21 (m, 2H), 2.16-2.01 (m, 2H), 1.93-1.85 (m, 1H), 1.62-1.53 (m, 1H) ppm. LC/MS: Rt=1.38 min, ES+ 442 (FA standard).
