Reaction Steps

The compound (170 mg) obtained in Step 2 of Example 37 was dissolved in tetrahydrofuran (6 mL). To the solution, triphenylphosphine (137 mg), 4-hydroxypyridine (50 mg), and a 40% solution of diisopropyl azodicarboxylate in toluene (276 μL) were added, and the mixture was stirred at 55° C. for 5.5 hours. The solvent in the reaction solution was distilled off under reduced pressure, and the obtained residue was purified by silica gel column chromatography (eluting solvent: hexane/ethyl acetate=7/3-ethyl acetate) to obtain the title compound (51 mg).
