Procedure

A mixture of {4-[5-({5-acetyl-4H,5H,6H,7H-pyrazolo[1,5-a]pyrazin-2-yl}amino)-1-methyl-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}pyridin-3-yl}methyl acetate 247a (100 mg, 0.16 mmol) and lithium hydroxide (96 mg, 4.0 mmol) in i-propanol/THF/water (2:2:1, 10 mL) was stirred at 35° C. for 30 min. The mixture was concentrated under reduced pressure. To the residue was added water (5 mL) and the resulting mixture was extracted with dichloromethane three times. The combined organic layer was then concentrated under reduced pressure and the resulting residue was purified by reverse-phase prep-HPLC to afford 247 (51 mg, 53%).
