Dimethylamine → 2-Amino-N,N-dimethyl-3-nitrobenzamide

Participants

Reaction Steps

EDC.HCl (2.47 g, 12.88 mmol) was added to a stirred mixture of 2-amino-3-nitrobenzoic acid (2.18 g, 11.98 mmol) (Mickelson, J. Med. Chem., 39(23) 4662 (1996)), 2M dimethylamine in THF (6.45 ml, 12.9 mmol) and 1-hydroxybenzotriazole (0.1 g, 0.74 mmol) in dichloromethane (100 ml). The reaction mixture was stirred at room temperature for 18 h, washed with saturated aqueous sodium bicarbonate and the organic layer dried (Na2SO4) and evaporated in vacuo to afford the title compound as a pale orange gum (2.5 g, 100%).
