To a solution of 3-[1-methyl-5-({5-[4-(oxetan-3-yl)piperazin-1-yl]pyridine-2-yl}amino)-6-oxo-1,6-dihydropyridin-3-yl]-5-{6-oxo-8-thia-5-azatricyclo[7.4.0.02,7]trideca-1(9),2(7)-dien-5-yl}pyridine-4-carbaldehyde 105g (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 105 (90 mg, 65%).
