Procedure

4-chloro-N1-methylbenzene-1,2-diamine (15.0 g, 96 mmol) and glycolic acid (8.1 g, 106 mmol) were mixed together in a sealed tube. The mixture was heated at 150° C. for 5 hours before it was cooled down to room temperature. The residue was purified by flash column chromatography (0-5% MeOH in CH2Cl2) to give the product (8.5 g, 45% yield). 1H NMR (300 MHz, CDCl3) δ: 3.80 (s, 3H), 4.86 (s, 2H), 7.13-7.22 (m, 2H), 7.62-7.64 (m, 1H).
