실험 절차

A mixture of 7-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-2,3,4,5-tetrahydro-1H-3-benzazepine hydrochloride (Example 17) (200 mg, 0.52 mmol), 1,1-dimethylethyl 2-propenoate (151 μL, 1.04 mmol) and diisopropylethylamine (453 μL, 2.60 mmol) in methanol (5 ml) was heated in the microwave at 90° C. for 30 minutes before the solvent was removed in vacuo. The residue was dissolved in 4M HCl (2 ml) in dioxane and the mixture stirred at room temperature for 5 h. The solvent was removed in vacuo and the residue purified by MDAP. To the product containing fractions was added 2M HCl and the solution concentrated in vacuo to give the title compound as a white solid (116 mg, 0.24 mmol). δH (d6DMSO, 400 MHz): 12.73 (1H, br.s), 10.76 (1H, br.s), 8.19 (1H, d), 8.11 (1H, dd), 7.98 (1H, d), 7.93 (1H, dd), 7.46 (1H, d), 7.45 (1H, d), 4.89 (1H, septet), 3.76-3.64 (2H, m), 3.44-3.31 (4H, hidden under H2O peak), 3.25-3.03 (4H, m), 2.89 (2H, t), 1.37 (6H, d). MS (ES): C24H2635ClN3O4 requires 455; found 456 [M+H]+.
