Reaction Steps

Methyl 5-amino-2,4-dimethylbenzoate (0.752 g, 4.20 mmol) in 5 mL water was cooled with an ice bath. H2SO4 (1.1 mL, 21 mmol) was added followed by a solution of sodium nitrite (0.301 g, 4.4 mmol) in 3 mL of water. The reaction was stirred in an ice bath for 30 min, and then in a 100° C. oil bath for 60 min. The reaction was cooled to rt and partitioned between EtOAc and brine. The organic phase was dried (Na2SO4) and concentrated to give the title compound as a yellow oil. 1H NMR (CDCl3) δ 7.48 (s, 1H), 7.00 (s, 1H), 5.95 (bs, 1H), 3.90 (s, 3H), 2.50 (s, 3H), 2.28 (s, 3H).
