Sodium triacetoxyborohydride (100 mg, 0.47 mmol) was added to a solution of 2-[2-(12-aza-tricyclo[7.2.1.0*2,7*]dodeca-2(7),3,5-trien-4-ylamino)-5-chloro-pyrimidin-4-ylamino]-N-methyl-benzamide (100 mg, 0.23 mmol), acetone (0.034 mL, 0.47 mmol), acetic acid (1 drop) and dichloroethane (5 mL). The reaction was stirred at room temperature for 18 h. The reaction was then quenched with saturated aqueous NaHCO3 (5 mL), extracted with CH2Cl2 (2×5 mL), dried over MgSO4, filtered, and concentrated to afford the title compound as off-white solid (89 mg, 82%). 1HNMR (400 MHz, DMSO-d6) δ 11.6 (s, 1H), 9.3 (s, 1H), 8.8-8.7 (m, 2H), 8.2 (s, 1H), 7.8 (d, 1H, J=7.8 Hz), 7.5 (appt t, 1H, J=8.1 Hz), 7.4 (d, 1H, J=8.6), 7.3 (s, 1H), 7.1 (appt t, 1H, J=7.6 Hz), 6.9 (d, 1H, J=8.3 Hz), 3.9 (m, 1H), 3.6 (m, 1H), 3.0 (dd, 1H, J=17.2, 4.6 Hz), 2.8 (d, 3H, J=4.3 Hz), 2.4 (m, 1H), 2.2 (d, 1H, J=17.2 Hz), 2.1-2.0 (m, 2H), 1.6 (m, 1H), 1.5 (m, 1H), 1.1 (d, 3H, J=5.9 Hz), 0.9 (d, 3H, J=5.9 Hz); MS (m/e) 477 (M+1); mp 202-205° C.
