Chloroacetonitrile → HCID 14116886, compound

Participants

Reaction Steps

To a stirred suspension of sodium hydride (420 mg of 60%, 10.5 mmoles, washed with n-pentane) in 10 ml DMF was added 4-amino-5-chloro-N-[2-(diethylamino)ethyl]-2-hydroxybenzamide hydrochloride (1.612 g, 5 mmoles) and the mixture stirred for 20 minutes, followed by cooling (ice bath) and addition of chloroacetonitrile (418 mg, 5.5 mmoles) and sodium bromide (100 mg). The mixture was stirred in the cold for 1 hour and at ambient temperature for 16 hours, followed by pouring into a mixture of water and ice, and filtration of the resulting solid. The product was dissolved in methylene chloride and filtered over alumina, followed by concentration in vacuo to give crude product. This was recrystallized from methanol to give 930 mg (57%) of the title compound as white crystalline solid mp 188°-189°. The NMR spectrum (90 MHz) in CDCl3 gave the following resonances: δ 8.1 (s, 1H); 7.78 (bs, 1 H); 6.44 (s, 1H); 4.84 (s, 2H); 4.60 (s, 2H); 3.43 (m, 2H); 2.59 (m, 6H); 1.02 (t, 6H).
