Procedure

A solution of the compound (90 mg, 0.23 mmol) obtained in step 5, 4-(aminomethyl)tetrahydropyran (0.029 mL, 0.26 mmol), DIEA (0.049 mL, 0.28 mmol) and HATU (107 mg, 0.28 mmol) in DMF (2.0 mL) was stirred at room temperature for 14 hr. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine and dried, and the solvent was evaporated under reduced pressure. The obtained residue was purified by NH-silica gel column chromatography (solvent gradient; 50→80% ethyl acetate/hexane) and crystallized from ethyl acetate and hexane to give the title compound (52.7 mg, 0.110 mmol, 46.7%) as a white powder.
