Reaction Steps

THF-diethyl ether solution (2.5 mL-2.5 mL) was added a solution of the compound obtained in step 1 (0.51 g) in THF-diethyl ether (2.5 mL-2.5 mL), and the resulting mixture was stirred at room temperature for 2 hr under a nitrogen atmosphere. 1N Aqueous sodium hydroxide solution (0.076 mL), saturated aqueous ammonium chloride (0.076 mL) and water (0.076 mL) were added, and the resulting mixture was stirred at room temperature for 3 hr. The precipitate was removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (solvent gradient; 0→40% ethyl acetate/hexane) to give 4-benzyl-8-(4-chlorophenoxy)-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine (0.20 g, 42%) as a white powder.
