실험 절차

A solution of methyl 4-(3-(5-(3,4-difluorobenzylcarbamoyl)-2-fluorophenylcarbamoyl)imidazo[1,2-a]pyridin-7-yl)-2-fluorobenzoate (Example 7.1, step 1) (497 mg, 0.862 mmol) and 2M NaOH (4311 μL, 8.62 mmol) in MeOH (2874 μL) was stirred at RT overnight. The solvent was removed in vacuo and the residue was acidified with 2M HCl to pH 2 and extracted with DCM. The organic extracts were dried over MgSO4, filtered and concentrated in vacuo to afford the title compound;
