Reaction Steps

5-[2-Cyclopropyl-5-(2,4-difluorophenyl)-1H-imidazol-4-yl]-N-[(1S)-3-methoxy-1-methyl-propyl]oxazolo[5,4-b]pyridin-2-amine (0.090 g, 0.23 mmol) is dissolved in a 1:1 mixture of dichloromethane and methanol (3 mL total). A 0.5 M solution of methanesulfonic acid in methanol (0.47 mL) is added dropwise to the solution. The mixture is stirred at RT for 30 min and then the solvent is evaporated under reduced pressure. The residue is mixed with methanol and concentrated twice to afford the title compound (0.111 g, 89%). LC-ES/MS m/z 440 (M+1).
