Procedure

Ethyl 3-[9-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-2,3-dihydro-1,4-benzoxazepin-4(5H)-yl]propanoate (Preparation 88) (60 mg, 0.123 mmol) was dissolved in ethanol (5 ml). 2M sodium hydroxide (0.309 ml, 0.617 mmol) was added and the reaction mixture was stirred at 60° C. for 4 h. The solvent was evaporated then the reaction mixture was diluted with water and neutralised with 2M hydrochloric acid and extracted with ethyl acetate. The organic phase was washed with water, dried and evaporated to give the product as a colourless solid (27 mg).
