To a solution of 3-chloro-4-phenyl-1-(pyridin-3-ylmethyl)-1H-pyrrole-2,5-dione (0.50 mmol, 149 mg) in DMF (1 mL) was added 4-methoxyaniline (1.10 mmol, 135 mg) The mixture was heated in a microwave reactor at 150° C. for five min. After cooling, the reaction mixture was purified by HPLC (95% 0.1M ammonium acetate buffer: 5% CH3CN→100% CH3CN) to give 77 mg (40%) of the title compound. 1H NMR (400 MHz, CDCl3) δ 8.71 (d, J=1.8 Hz, 1H), 8.54 (dd, J1=4.7 Hz, J2=1.6 Hz, 1H), 7.80-7.75 (m, 1H), 7.35 (bs, 1H), 7.26 (dd, J1=7.8 Hz, J2=4.7 Hz, 1H), 7.15-7.05 (m, 3H), 6.98-6.94 (m, 2H), 6.62-6.50 (m, 4H), 4.78 (s, 2H), 3.68 (s, 3H).
