Procedure

N-{(1R,2R)-2-[2-(10-Aza-tricyclo[6.3.2.0*2,7*]trideca-2,4,6-trien-4-ylamino)-5-chloro-pyrimidin-4-ylamino]-cyclohexyl}-methanesulfonamide (77 mg, 0.157 mmol) was placed in 1,2-dichloroethane (5 mL) and acetic acid (0.25 mL). Acetone (13.6 mg, 0.235 mmol, 17.2 μL, 1.5 eq) was added and the reaction was stirred for 5 minutes. Sodium borohydride (7.0 mg, 0.188 mmol, 1.2 eq) was added and the reaction was heated at 80° C. overnight. The reaction was then diluted with CH2Cl2 (20 mL) and washed with water (20 mL). The organic layer was dried (sodium sulfate), filtered, and concentrated under reduced pressure. Purification by prep-HPLC using a gradient of 0-40% acetonitrile/water as the eluting solvent to obtain N-{(1R,2R)-2-[5-chloro-2-(10-Isopropyl-10-aza-tricyclo[6.3.2.0*2,7*]trideca-2,4,6-trien-4-ylamino)-pyrimidin-4-ylamino]-cyclohexyl}-methanesulfonamide as a mixture of diastereomers as an orange foam (14.63 mg, 17%). LCMS (m/e) 533 (M+1); 1H-NMR (CDCl3, 400 MHz) δ 7.91 (s, 1H), 7.26-7.18 (m, 2H), 7.01 (d, 1H, J=6.7 Hz), 6.90 (bs, 1H), 5.49 (bs, 1H), 5.39-5.33 (m, 1H), 3.92-3.78 (m, 1H), 3.30-3.17 (m, 1H), 3.00-2.92 (m, 2H), 2.92-2.75 (m, 3H), 2.77 (s, 3H), 2.40-2.27 (m, 2H), 2.26-2.10 (m, 4H), 1.87-1.75 (m, 2H), 1.65-1.50 (m, 2H), 1.42-1.25 (m, 4H), 0.94 (d, 6H, J=6.5 Hz).
