Procedure
3-[(3,4-Dichloro-benzyl-methyl-carbamoyl]-2-hydroxy-acrylic acid methyl ester (Compound 12-B) was treated with paraformaldehyde and methyl-ethane-1,2-diamine as described in the preparation of Compound 12. The title compound was triturated with EtOAc to give a white solid (7.8 mg, 4% yield). 1H NMR (300 MHz, CDCl3) δ: 9.14, (bs, 1H), 7.40, (d, 1H, J=8.05), 7.34 (s, 1H), 7.11 (dd, 1H, J=8.05, J=1.10), 4.58, (s, 2H), 4.34, (s, 2H), 3.94 (m, 2H), 3.25 (m, 2H), 3.03 (s, 3H), 2.78 (s, 3H). HRMS (M+H) calcd for C16H19N3Cl2O3: 372.0881. found: 372.0886.
