Reaction Steps

To a solution of 5-(2-azidopropoxy)-2-(3-chloro-4-(cyclopropylmethoxy)phenyl)-4,5,6,7-tetrahydro-1,3-benzoxazole (3.40 g) in THF (30 mL) were added triphenylphosphine (2.66 g) and water (5 mL), and the mixture was stirred overnight at 60° C. The solvent was evaporated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (NH, hexane/ethyl acetate). To the obtained oil were added pyridine (10 mL) and acetic anhydride (10 mL), and the mixture was stirred at room temperature for 10 min. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate/methanol) to give the title compound (3.02 g).
