Procedure

A mixture of 1-(4-(5-isopropyl-1H-pyrazol-3-ylamino)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-2-yl)pyrrolidine-2-carboxylic acid (1 g, 2.8 mmol), morpholine (0.366 g, 4.2 mmol), HATU (1.28 g, 3 mmol) and DIPEA (0.58 g, 4 mmol) in DMF (5 mL) was allowed to stir at RT overnight. The reaction mixture was diluted with water (50 mL) and extracted with EtOAc (2×50 mL). The combined organic layer was washed with water (8×25 mL) and dried over anhydrous sodium sulfate. Removal of EtOAc gave an oily residue which was purified by reverse phase HPLC followed by chiral HPLC to afford 15 mg of (R)-(1-(4-(5-isopropyl-1H-pyrazol-3-ylamino)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-2-yl)pyrrolidin-2-yl)(morpholino)methanone, and its enantiomer. 1H NMR (400 MHz, CD3OD, freebase) δ (ppm): 1.29 (d, 6H), 1.92-2.15 (m, 5H), 2.30-2.42 (m, 1H), 2.67-2.81 (m, 4H), 2.90-3.04 (m, 1H), 3.41-3.90 (m, 10H), 4.98-5.08 (m, 1H), 5.85 (brs, 1H).
