A solution of carboxamide 1-E (0.64 g, 1.7 mmol) and cyanuric chloride (0.47 g, 2.53 mmol) in DMF (15 ml) was stirred at room temperature under a nitrogen atmosphere. After 2 h, DMF was removed in vacuo and the solid was redissolved in methylene chloride (100 ml). This solution was washed with saturated aqueous sodium bicarbonate and brine, dried (Na2SO4), and stripped to give 1-F as a pale yellow solid. MS (ESI+)=361.3 (M+1); 1H NMR (500 MHz, CDCl3): δ2.15 (6H, m), 2.22 (6H, m), 3.47 (3H, s), 7.51 (1H, m), 7.72 (2H, m), 7.87 (1H, m) ppm.
