Procedure

To a solution of 4-[1-methyl-5-({5-[(2S)-2-methyl-4-(oxetan-3-yl)piperazin-1-yl]pyridin-2-yl}amino)-6-oxo-1,6-dihydropyridin-3-yl]-2-{6-oxo-8-thia-4,5-diazatricyclo-[7.4.0.02,7]trideca-1(9),2(7),3-trien-5-yl}pyridine-3-carbaldehyde 191k (118 mg, 0.18 mmol) in methanol/dichloromethane (10/10 mL) was added NaBH4 (21 mg, 0.54 mmol) at room temperature. After the reaction was stirred for 1 h, LCMS indicated the reaction was completed. Then the mixture was poured into water (20 mL) and concentrated under reduced pressure. The residue was extracted with dichloromethane (20 mL×3). The combined organic layer was washed with brine (30 mL), dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue solid was purified by reverse-phase prep-HPLC to afford 191 (71 mg, 60%) as white solid.
