Ethyl 3-(3-(5-(3,4-difluorobenzylcarbamoyl)-2-fluorophenylcarbamoyl)imidazo[1,2-a]pyridin-7-yl)propanoate (step 1) (50 mg, 0.095 mmol) was suspended in dry ether and cooled to 0° C. Methylmagnesium bromide (0.318 ml, 3.0M in ether, 0.953 mmol) was added and the mixture was stirred and allowed to warm to RT over 16 hrs. The mixture was partitioned between 10% aq. Citric acid and EtOAc. The organics were separated, dried (MgSO4), filtered and evaporated to dryness. The residue was purified by chromatography on silica eluting with 0-10% MeOH in DCM to afford the title product;
