Sodium Hydroxide → HCID 68428722, compound

Participants

Reaction Steps

To a mixture of lithium aluminum hydride (0.079 g) and 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 (0.079 mL), saturated aqueous ammonium chloride (0.079 mL) and water (0.079 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-(3-chlorophenoxy)-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine (0.25 g, 49%) as a white powder.
