Procedure

N-(4-(1-(4-methoxybenzyl)-3-(piperidin-4-ylmethyl)-1H-pyrazolo[3,4-b]pyridin-4-yloxy)-3-fluorophenyl)-4-(4-fluorophenyl)-3-oxo-3,4-dihydropyrazine-2-carboxamide (17 mg, 0.025 mmol; prepared as in Example 152, Step B) was added to a small round bottom flask and dissolved in dry THF (1.5 mL). Acetaldehyde (5.56 mg, 0.126 mmol) and a drop of acetic acid (d 1.049) were added. The reaction mixture was stirred for 10 minutes under N2(g) at room temperature. NaBH(OAc)3 (53.5 mg, 0.252 mmol) was added and stirred at room temperature for 1 hour. The reaction mixture was partitioned between water and DCM and extracted with a second portion of DCM (10 mL). The combined organics were dried over sodium sulfate and evaporated to afford desired product, used as crude in next step. Yield 18.6 mg, 90% purity by HPLC, 94%. LRMS (APCI pos) m/e 706.3 (M+H).
