실험 절차

Ethyl 4-[(3-cyclobutyl-2,3,4,5-tetrahydro-1H-3-benzazepin-7-yl)oxy]butanoate (E167a) (1.5 g, 4.5 mmol) was diluted in ethanol (30 ml) and treated with 2N sodium hydroxide (7.9 ml). After stirring at reflux for 24 hours, the reaction mixture was cooled to room temperature, filtered and concentrated in vacuo. The crude mixture was applied to a SCX ion exchange cartridge (Varian bond-elute) and washed with water, methanol and then a mixture of 0.880 ammonia:methanol (1:9). The combined basic fractions were reduced in vacuo to afford the title compound (E167b) as the ammonium salt. MS (ES+) m/e 303 [M+H]+
