反応手順
Methyl 3-(3-(4-methyl-3-(6-(((methylsulfonyl)oxy)methyl)imidazo[1,2-a]pyridine-3-carboxamido)phenyl)-1,2,4-oxadiazol-5-yl)azetidine-1-carboxylate (133) (15.0 mg, 0.028 mmol) and K2CO3 (8.3 mg, 0.06 mmol) in 2,2-difluoroethanol (0.5 mL) was heated at 120° C. for 5 minutes. The reaction mixture was purified by preparative HPLC to afford methyl 3-(3-(3-(6-((2,2-difluoroethoxy)methyl)imidazo[1,2-a]pyridine-3-carboxamido)-4-methylphenyl)-1,2,4-oxadiazol-5-yl)azetidine-1-carboxylate (F95). MS m/z 527.1 (M+1)+.
