Procedure
Carbonyl diimidazole (142 mg, 0.88 mmol) was added to a stirred solution of 6-[(3-cyclobutyl-2,3,4,5-tetrahydro-1H-3-benzazepin-7-yl)oxy]-3-pyridinecarboxylic acid (E196b) (150 mg, 0.44 mmol) in dichloromethane (5 ml). After stirring at room temperature for 3 hours, cyclopropylamine (0.15 ml, 2.2 mmol) was added and the mixture was allowed to stir for a further 18 hours. The reaction mixture was applied to a SCX ion cartridge (Varian bond-elute, 10 g) and washed with methanol and then a mixture of 0.880 ammonia:methanol (1:9). The combined basic fractions were concentrated in vacuo to afford the title compound (E196). MS (ES+) m/e 378 [M+H]+.
