A solution of N-(4-(1-(4-methoxybenzyl)-3-(4-(dimethylamino)piperidin-1-yl)-1H-pyrazolo[3,4-b]pyridin-4-yloxy)-3-fluorophenyl)-3-(4-fluorophenyl)-2-oxo-3-aza-bicyclo[3.1.0]hexane-1-carboxamide (30 mg, 0.042 mmol) was heated in TFA (2 mL) for 4 hours. Excess TFA was evaporated and the residue was purified on a SCX column (7N ammonia in MeOH) to afford the product (17 mg, 68% yield) as a yellow solid. LRMS (APCI pos) m/e 588.2 (M+1). 1H NMR (400 MHz, CDCl3) δ 10.50 (s, 1H), 9.80 (s, 1H), 8.30 (s, 1H), 7.78-7.90 (m, 1H), 7.40-7.60 (m, 2H), 7.00-7.40 (m, 4H), 6.10-6.20 (m, 1H), 4.00-4.20 (m, 4H), 3.70-3.80 (m, 1H), 2.80-3.00 (m, 4H), 2.40 (s, 6H), 1.20-2.10 (m, 5H).
