Procedure

A neat mixture of (1S,2R,4R)-4-({6-[(1S)-2,3-dihydro-1H-inden-1-ylamino]pyrimidin-4-yl}amino)-2-(hydroxymethyl)cyclopentanol (100. mg, 0.294 mmol) and 2,6-di-tert-butyl-4-methylpyridine (181 mg, 0.881 mmol) was dissolved in ACN (5.00 mL) before tert-butyl (chlorosulfonyl)carbamate (95.0 mg, 0.441 mmol, as prepared in Example 21c) was added. The reaction was stirred for 2 h before being quenched via addition of MeOH (2 mL). The resulting mixture was concentrated in vacuo and purified via silica gel chromatography eluting with a gradient of 10 to 20% MeOH in DCM to afford the title compound as an amorphous solid (50.0 mg, 33%). LC/MS: Rt=1.24 min, ES+ 520. (AA standard).
