Reaction Steps

A mixture of tert-butyl (2-chloro-4-formylpyridin-3-yl)carbamate (7-3) (300 mg, 1.17 mmol), tert-butyl {1-[4-(phenylacetyl)phenyl]cyclobutyl}carbamate (4-1) (427 mg, 1.17 mmol) and potassium carbonate (485 mg, 3.51 mmol) in DMF (10 mL) was stirred at 120° C. for 15 hours. The reaction mixture was cooled to room temperature, diluted with ethyl acetate, washed with water, dried over sodium sulfate, filtered, and concentrated in vacuo. The residue was purified by silica gel chromatography (hexane-EtOAc) to give tert-butyl {1-[4-(8-chloro-3-phenyl-1,7-naphthyridin-2-yl)phenyl]cyclobutyl}carbamate (7-4) as a pale yellow solid.
