2-Chloro-N-(propylcarbamoyl)acetamide → HCID 59202067, compound

Participants

Reaction Steps

Following general procedure A, methyl hydrogen fumarate (MHF) (0.50 g, 3.84 mmol) dissolved in NMP was reacted at ca. 55° C. with 1-(2-chloroacetyl)-3-propyl urea (0.82 g, 4.60 mmol) in the presence of CsHCO3 (0.89 g, 4.61 mmol) to provide 0.02 g (2% yield) of the title compound (19) as a white solid. Addition of methanol (MeOH) afforded 0.49 g (48% yield) of white solid. 1H NMR (CDCl3, 400 MHz): δ 6.90-6.99 (m, 2H), 4.77 (s, 2H), 3.82 (s, 3H), 3.25-3.24 (q, 2H, J=5.6 Hz), 1.57-1.55 (q, 2H, J=7.2 Hz), 0.95-0.91 (t, 3H, J=7.6 Hz). MS (ESI): m/z 273.08 (M+H)+.
