Triethylamine → N-(5-bromothiazol-2-yl)-5-chloro-2-methoxybenzamide

Participants

Reaction Steps

To a solution of 2-amino-5-bromothiazole (1220 mg, 6.81 mmol) in dichloromethane (10 ml) was added triethylamine (1.235 ml, 8.86 mmol) and 4-dimethylamino pyridine (83 mg, 0.681 mmol), followed by addition of 5-chloro-2-methoxybenzoyl chloride (1397 mg, 6.81 mmol) and stirred overnight. The reaction was concentrated and water was added to the residue. The mixture was sonicated and filtered to obtain the title compound as off-white solid (1.56 g, 66%). 1H NMR (300 MHz, DMSO-D6) δ ppm 3.88 (m, 3H) 7.23 (d, J=8.81 Hz, 1H) 7.58-7.67 (m, 3H) 12.32 (s, 1H); MS (DCI/NH3) m/z 347 (M+H)+.
