Triethylorthoaceate → 3-Cyclobutyl-7-{[5-(5-methyl-1,3,4-oxadiazol-2-yl)-2-pyridinyl]oxy}-2,3,4,5-tetrahydro-1H-3-benzazepine

Participants

Reaction Steps

A mixture of triethylorthoacetate (3 ml) and 6-[(3-cyclobutyl-2,3,4,5-tetrahydro-1H-3-benzazepin-7-yl)oxy]-3-pyridinecarbohydrazide (D54) (185 mg, 0.52 mmol) was heated at reflux for 16 hours. The reaction mixture was concentrated and the resulting residue was purified by column chromatography eluting with a mixture of 0.880 ammonia:methanol:dichloromethane (0.1:5:95) to afford the title compound (E216). MS (ES+) m/e 377 [M+H]+.
