Procedure

To a solution of (S)—N-(6-fluoropyridin-3-yl)-1-(4-(5-isopropyl-1H-pyrazol-3-ylamino)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-2-yl)pyrrolidine-2-carboxamide (250 mg, 0.55 mmol) in 1,4-dioxane (5 mL) was added aqueous ammonia (5 mL) and the reaction mixture was allowed to reflux in steel bomb at 130° C. for 18 h. The reaction mixture was concentrated under vacuum to obtain an oily crude product which was purified by reverse phase HPLC to afford 8 mg of (S)—N-(6-aminopyridin-3-yl)-1-(4-(5-isopropyl-1H-pyrazol-3-ylamino)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-2-yl)pyrrolidine-2-carboxamide. 1H NMR (400 MHz, CD3OD, freebase) δ (ppm): 1.20 (d, 6H), 2.00-2.20 (m, 4H), 2.75-2.95 (m, 5H), 3.50-3.90 (m, 4H), 4.90-4.98 (m, 1H), 6.40 (s, 1H), 6.50 (d, 1H), 7.40 (s, 1H), 7.90 (s, 1H). The other enantiomer is prepared using the chiral (R) starting material.
