Versuchsvorschrift
A stirred slurry of 2-(1-ethoxycarbonyl-2-vinyl-cyclopropylcarbamoyl)-4-(isoquinolin-1-yloxy)-pyrrolidine-1-carboxylic acid tert-butyl ester (5.40 g, 10.9 mmol) was treated with 2N HCl/ether (Aldrich)(250 mL) for 24 h. The reaction mixture was concentrated in vacuo to give 5.3 g (˜100%) of 1-{[4-(isoquinolin-1-yloxy)-pyrrolidine-2-carbonyl]-amino}-2-vinyl-cyclopropanecarboxylic acid ethyl ester, bis hydrochloride as a white solid: LC-MS (Method A, retention time: 2.40 min), MS m/z 396 (M++1).
