Versuchsvorschrift
1,1-Dimethylethyl 7-(5-{5-chloro-6-[(1-methylethyl)oxy]-3-pyridinyl}-1,2,4-oxadiazol-3-yl)-1,2,4,5-tetrahydro-3H-3-benzazepine-3-carboxylate (Preparation 96) (305 mg, 0.629 mmol) in dichloromethane (2 mL) at room temperature was treated with trifluoroacetic acid (1 ml, 12.98 mmol) and the mixture stirred for 1 hr. The reaction mixture was concentrated and the residue partitioned between 2M NaOH and ethyl acetate. The ethyl acetate extract was washed with brine, dried and concentrated to a colourless gum which slowly crystallized, to give the title compound free base (229 mgs).
