3-methoxypropanal

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of methyl 7-bromo-2,3-dihydro-1H-1-benzazepine-4-carboxylate (0.80 g) and 3-methoxypropionaldehyde (1.25 g) in 1,2-dichloroethane (10 ml) was added sodium triacetoxyborohydride (1.81 g) at room temperature, and the mixture was stirred for 24 hours. Water was added to the reaction system, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried with magnesium sulfate. After concentration under reduced pressure, the resulting residue was separated and purified with column chromatography (ethyl acetate hexane=1:3→1:2) to give methyl 7-bromo-1-(3-methoxypropyl)-2,3-dihydro-1H-1-benzazepine-4-carboxylate (935 mg) as yellow oil. the mixture was extracted with ethyl acetate The organic layer was washed with saturated brine dried with magnesium sulfate After concentration under reduced pressure the resulting residue was separated purified with column chromatography (ethyl acetate hexane=1:3→1:2)
