実験手順: 2-[1-(3-Ethoxy-4-methoxyphenyl)-2-(N,N-dimethylaminosulfonyl)ethyl]isoindolin-1-one was prepared by the procedure of Example 3 from 1-(3-ethoxy-4-methoxyphenyl)-2-(N,N-dimethylaminosulfonyl)ethylamine (150 mg, 0.49 mmol) and 1,2-phthalic dicarboxaldehyde (67 mg, 0.49 mmol) in acetic acid (2 mL). The product was obtained as a solid (142 mg, 69% yield): mp, 165.0-167.0° C.; 1H NMR (CDCl3) δ 1.45 (t, J=7 Hz, 3H, CH3), 2.86 (s, 6H, N(CH3)2), 3.58 (dd, J=4.7, 14.4 Hz, 1H, CHH), 3.86 (s, 3H, CH3), 4.08 (q, J=7 Hz, 2H, CH2), 4.30 (d, J=16.5 Hz, 1H, NCHH), 4.33 (dd, J=9, 14.4 Hz, 1H, CHH), 4.49 (d, J=16.5 Hz, 1H, NCHH), 5.60 (dd, J=4.7, 9.5 Hz, 1H, NCH), 6.83 (d, J=8.3 Hz, 1H, Ar), 6.98 (dd, J=2, 8.3 Hz, 1H, Ar), 7.06 (d, J=2 Hz, 1H, Ar), 7.37-7.56 (m, 3H, Ar), 7.84 (d, J=7 Hz, 1H, Ar), 13C NMR (CDCl3) δ 14.69, 37.31, 48.64, 49.73, 52.91, 52.95, 64.54, 111.31, 112.46, 119.29, 122.76, 123.72, 128.03, 130.67, 131.55, 132.75, 141.26, 148.73, 149.39, 168.63; Anal Calcd for C21H26NO5S: C, 60.27; H, 6.26; N, 6.69.

実験手順: A stirred mixture 1-(3-ethoxy-4-methoxyphenyl)-2-methylsulfonylethylamine (100 mg, 0.37 mmol) and 1,2-phthalic dicarboxaldehyde (49 mg, 0.37 mmol) in acetic acid (2 mL) was heated to reflux for 15 min. Removal of solvent in vacuo and chromatography gave an oil which was stirred with ether (2 mL). The resulting suspension was filtered to yield 2-[1-(3-ethoxy-4-methoxyphenyl)-2-methylsulfonylethyl]isoindolin-1-one as a light yellow solid (100 mg, 70% yield): mp, 130.0-134.0° C.; 1H NMR (CDCl3) δ 1.45 (t, J s=7 Hz, 3H, CH3), 2.96 (s, 3H, CH3), 3.70 (dd, J=4.5, 14.7, Hz, 1H, CHH), 3.86 (s, 3H, CH3), 4.07 (q, J=6.9 Hz, 2H, CH2), 4.25 (d, J=16.5 Hz, 1H, CHH), 4.31 (dd, J=10.3, 14.5 Hz, 1H, CHH), 4.46 (d, J=16 HZ, 1H, CHH), 5.71 (dd, J=4.5, 10.3 Hz, 1H, NCH), 6.84-7.01 (m, 3H, Ar), 7.38-7.56 (m, 3H, Ar), 7.85 (d, J=6.9 Hz, 1H, Ar); 13C NMR (CDCl3) δ 14.65, 41.33, 46.27, 52.33, 55.95, 56.00, 65.56, 111.45, 112.28, 119.30, 122.85, 123.85, 128.13, 129.89, 131.80, 132.27, 141.26, 148.88, 149.62, 169.09; Anal Calcd for C20H23NO5S: C, 61.68; H, 5.95; N, 3.60.

実験手順: 0.32 g (0.76 mmol) of 2-(2R)-(4-chlorobiphenylsulfonylamino)-5-amino-pentanoic acid hydrochloride is dissolved in 30 ml of glacial acetic acid with 0.186 g (1.35 mmol) of phthalaldehyde and stirred at 100° C. for 3 hours. The solution is cooled to 0° C., and the precipitate which is deposited is filtered off with suction and chromatographed on a silica gel column (eluent: ethyl acetate/petroleum ether/glacial acetic acid 10/10/2). The solution is cooled to 0° C. the precipitate which is deposited is filtered off with suction chromatographed on a silica gel column (eluent: ethyl acetate/petroleum ether/glacial acetic acid 10/10/2)
