Versuchsvorschrift

To a solution of 3-(4-acetylamino-1,3-dioxo-1,3-dihydro-isoindol-2-yl)-3-(3-cyclopropylmethoxy-4-difluoromethoxy-phenyl)-propionic acid (100 mg, 0.22 mmol) in tetrahydrofurane was added carbonyldiimidazole (53 mg, 0.33 mmol) at room temperature. The solution was stirred for 2 hours at room temperature. To the mixture was added ammonium hydroxide (0.05 ml, 0.66 mmol). The resulted mixture was stirred at room temperature for 2 hours. Water (5 ml) was added to the reaction mixture. THF was removed in vacuo and the resulted mixture was taken up in ethyl acetate (20 ml). The organic layer was washed with saturated sodium bicarbonate solution (3×10 ml), water (10 ml), brine (10 ml) and was dried over magnesium sulfate. The solvent was removed in vacuo. The resulted oil was purified by HPLC (acetonitrile:water=45:55) to give 3-(4-acetylamino-1,3-dioxo-1,3-dihydro-isoindol-2-yl)-3-(3-cyclopropylmethoxy-4-difluoromethoxy-phenyl)-propionamide as a white solid (80 mg, 81%): mp 77-79° C.; 1HNMR (CDCl3): δ 0.32-0.38 (m, 2H), 0.60-0.67 (m, 2H), 1.20-1.31 (m, 1H), 2.27 (s, 3H), 3.03 (dd, J=5.5, 15.5 Hz, 1H), 3.70 (dd, J=8.4, 15.5 Hz, 1H), 5.28-5.40 (m, 1H), 5.74-5.80 (m, 1H), 5.79 (dd, J=5.8, 10.5 Hz, 1H), 6.60 (t, JH-F=75 Hz, 1H), 7.09-7.13 (m, 3H), 7.47 (d, J=7.3 Hz, 1H), 7.63 (t, J=7.5 Hz, 1H), 8.75 (d, J=8.5 Hz, 1H), 9.49 (s, 1H). 13C NMR (CDCl3): δ 3.8, 3.9, 10.74, 25.6, 38.1, 51.9, 474.5, 112.5, 114.8, 115.8, 116.7, 118.7, 120.8, 123.5, 125.6, 131.8, 136.7, 137.8, 138.1, 140.8, 151.2, 168.6, 169.9, 170.5, 172.1; Anal.
