Procedure

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer was charged with (4-(5-(5-(2,2-dimethyl-4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-ylamino)-1-methyl-6-oxo-1,6-dihydropyridin-3-yl)-2-(1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)pyridin-3-yl)methyl acetate 190i (100 mg, 1 eq., 0.14 mmol), lithium hydroxide (54 mg, 10 eq., 1.4 mmol), i-propanol (3 mL), THF (3 mL) and water (2 mL). The mixture was stirred at 30° C. for 1 h. It was then filtered and the filtrate was concentrated under reduced pressure. The residue was purified by reverse-phase prep-HPLC to afford 190 as a white solid (43 mg, 46%).
