Versuchsvorschrift

To a solution of (1S)-2-chloro-N-{7-chloro-2-[1-(3-ethoxy-4-methoxy-phenyl)-2-methanesulfonyl-ethyl]-3-oxo-2,3-dihydro-1H-isoindol-4-yl}-acetamide (400 mg, 0.78 mmol) in CH3CN (10 ml) was added dimethylamine (2N in MeOH, 1.6 ml, 3.2 mmol). The mixture was heated at 70° C. for 2 hrs. The reaction mixture was concentrated on rota-vap and extracted with water (50 ml) and EtOAc (50 ml). The organic layer washed with water (50 ml), brine (25 ml), dried over Na2SO4 and concentrated. The resulted oil was purified by chromatography to give an oil which was stirred with HCl in ether (3 ml) to give (1S)—N-{7-chloro-2-[1-(3-ethoxy-4-methoxy-phenyl)-2-methanesulfonyl-ethyl]-3-oxo-2,3-dihydro-1H-isoindol-4-yl}-2-dimethylamino-acetamide; hydrochloride as a white solid (300 mg, 68% yield): mp, 198-200° C.; 1H NMR (DMSO-d6) δ 1.32 (t, J=7.5 Hz, 3H, OCH2CH3), 2.87 (s, 6H, N(CH3)2), 3.04 (s, 3H, CH3), 3.74 (s, 3H, CH3), 3.94-4.16 (m, 4H, —OCH2CH3+NCHH+CHHSO2), 4.36-4.50 (m, 3H, CHHSO2+CH2NCO), 4.73 (d, J=18 Hz, 1H, CHHN), 5.85-5.91 (m, 1H, NCH), 6.98 (s, 2H, Ar), 7.05 (s, 1H, Ar), 7.69 (d, J=8 Hz, 1H, Ar), 8.18 (d, J=8 Hz, 1H, Ar), 10.21 (bs, 1H, HCl); 10.45 (s, 1H, NHCO); 13C NMR (DMSO-d6) δ 15.17, 23.25, 41.51, 43.86, 46.03, 49.41, 53.88, 56.00, 58.52, 64.41, 112.50, 112.80, 120.23, 121.25, 123.33, 130.22, 133.21, 134.72, 140.60, 148.55, 149.46, 154.53, 167.02, 180.13, Anal Calcd for C24H31Cl2N3O6S+0.41 H2O: C, 50.78; H, 5.65; N, 7.40.
