Reaction Steps
To a solution of 2-(4-(cyclopropylmethoxy)-3-fluorophenyl)-4-fluoro-1,3-benzoxazol-6-ol (110 mg), tert-butyl ((2S)-1-hydroxypropan-2-yl)carbamate (91.0 mg) and triphenylphosphine (136 mg) in THF (5 mL) was added dropwise diisopropyl azodicarboxylate toluene solution (1.9 M, 0.274 mL) at 0° C., and the mixture was stirred at room temperature for 30 min. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (NH, hexane/ethyl acetate) to give the title compound (159 mg).
