Potassium tert-butoxide (0.132 g) in ethanol (4 ml) was stirred for 15 min before adding 1,1-dimethylethyl 7-(5-acetyl-2-{[(4-chloro-2-pyridinyl)methyl]oxy}phenyl)-1,2,4,5-tetrahydro-3H-3-benzazepine-3-carboxylate, (0.4 g) and this was heated in a microwave at 110 C. for 1.5 h. Water (20 ml) was added to the cooled mixture and this was extracted with DCM (2×30 ml). The combined organics were washed with brine, dried over sodium sulphate and concentrated in vacuo. The crude product was purified through silica eluting with 0-45% ethyl acetate in hexane to give the title compound, 0.16 g
