실험 절차

bis-(2-Chloroethyl)amine hydrochloride 26 (200 mg, 1.1 mmol) was dissolved in dichloromethane (15 mL) and triethylamine (0.45 mL, 3.3 mmol) was added. The mixture was stirred for 5 minutes at ambient temperature and methyl chlorothioformate (1.32 mmol) was added. The mixture was stirred until no bis-(2-chloroethyl)amine remained by TLC (ethyl acetate). N-mehty tyramine (322 mg, 2.1 mmol) was added and the mixture was heated under reflux for 4 hours. The mixture was allowed to cool, purified by dry flash column chromatography (silica gel, dichloromethane 200 mL) and concentrated in vacuo to yield prodrug 29 as an orange/brown oil (68 mg, 18%). νmax 3400, 1660, 1444, 1380, 1145/cm−1; δ 1H (400 MHz, CDCl3) 2.32 (3H, s, CH3) 2.60 (2H, t, J 3.72 Hz, CH2Ar), 3.17–3.22 (10H, m, ArCH2CH2, 2×CH2CH2Cl), 6.67 (2H, d, J 5.7 Hz, 2×ArH), 6.9 (2H, d, J 5.7 Hz, 2×ArH), 7.82 (1H, brs, NH); 13C (100 MHz, CDCl3) 30.1 (CH2), 43.3 (CH2), 44.1 (CH2), 44.2 (CH2), 45.2 (CH2), 46.5 (CH3) 46.6 (CH2), 115.9 (2×CH), 130 (2×CH), 130.1 (C), 155.6 (C), 161.5 (C). m/z (Cl) 283 (87%), 238 (50) 152 (100), 121 (45), 108 (35).
