Chloroacetyl chloride → HCID 86689957, compound

Participants

Reaction Steps

To a solution of 46a (3.0 g, 8.0 mmol) in THF (100 mL), chloroacetyl chloride (2.2 g, 20 mmol) in THF (50 mL) was added dropwise at RT and the resulting mixture was stirred at RT for additional 45 minutes. The reaction mixture was evaporated under reduced pressure and the solid residue was triturated with saturated aqueous solution of NaHCO3 and then filtered. The solid was washed successfully with water and hexane, and dried to yield N-(3-(3-(4-(bis(2-chloroethyl)amino)-phenyl)ureido)phenyl)-2-chloroacetamide, 2.8 g (82%); mp 232-233° C. 1H NMR (DMSO-d6) δ: 2.80-2.83 (2H, t, J=5.9 Hz, CH2), 3.68-3.71 (8H, m, CH2), 3.86-3.89 (2H, t, J=5.9 Hz, CH2), 6.70-6.72 (2H, d, J=8.5 Hz, Ar—H), 7.14-7.30 (5H, m, Ar—H), 7.76 (1H, s, Ar—H), 8.46 (1H, brs, NH), 8.73 (1H, brs, NH), 10.04 (1H, brs, NH).
