Reaction Steps

A solution of 6 (0.140 g), 2,3 - dimethylphenyl aniline (0.065 mL), and triethyl-amine (0.142 mL) in acetonitrile (10 mL) was refluxed 18 h. The solution was concentrated in vacuo and the residue was partitioned between methylene chloride and 2% potassium hydrogen sulfate. The methylene chloride was washed with saturated sodium chloride, dried over magnesium sulfate, and concentrated in vacuo to afford the the product as a solid. NMR (300 MHz, CDCl3) δ 8.46 (1H, d, J=8 Hz), 8.30 (1H, d, J=8 Hz), 7.77 (1H, t, J=8 Hz), 7.24 (1H, s ), 7.22 (1H, d, J=2 Hz), 7.12 (1H, m), 5.18 (2H, s), 2.35 (3H, s), 2.14(3H, s).
