Procedure

HATU (124 mg, 0.32 mmol) was added to a solution of (R)—N-(7-fluoro-1,1-dimethyl-2,3-dihydro-1H-inden-5-yl)-2-methoxy-5,6,7,8-tetrahydro-1,6-naphthyridine-5-carboxamide (100 mg, 0.27 mmol), DIEA (0.093 mL, 0.54 mmol) and the crude trans-cyclobutane-1,3-dicarboxylic acid (58.5 mg, 0.41 mmol) in DMF (2.0 mL) at room temperature, and the mixture was stirred at room temperature for 5 hr. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with brine, and dried over magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (solvent gradient; 20→90% ethyl acetate/hexane), and then preparative HPLC (C18, mobile phase: water/acetonitrile (containing 0.1% TFA)) to give the title compound (24.0 mg, 0.048 mmol, 17.89%) as a white solid.
