HCID 866841794-Hydroxymethyl-3-[1-methyl-5-({5-[4-(oxetan-3-yl)piperazin-1-yl]pyridine-2-yl}amino)-6-oxo-1,6-dihydropyridin-3-yl]-5-{4,4-dimethyl-9-oxo-7-thia-10-azatricyclo[6.4.0.02,6]dodeca-1(8), 2(6)-dien-10-yl}pyridine-4-carbaldehydeYield 45%

Procedure

To a solution of 106j (130 mg, 0.20 mmol) in methanol (5 mL) at 0° C. was added sodium borohydride (22 mg, 0.6 mmol) and stirred for 30 minutes. Then the reaction mixture was quenched with water (1.0 mL) and concentrated. The residue was purified by reverse-phase prep-HPLC to afford 106 (60 mg, 45%) as a yellow solid.
