Procedure

3-[(3,4-Dichloro-benzyl-methyl-carbamoyl]-2-hydroxy-acrylic acid methyl ester (Compound 12-B) was treated with paraformaldehyde and 3,4 dichloro-benzylamine as described in the preparation of Compound 12. The title compound was isolated as a white foam (155 mg, 66% yield). 1H NMR (500 MHz, CDCl3) δ: 10.70 (bs, 1H), 7.42 (d, 1H, J=3.05), 7.40 (d, 1H, J=3.05), 7.34 (d, 2H, J=1.83), 7.09 (dd, 2H, J=8.24, J=1.83), 4.62 (s, 2H), 4.57 (s, 2H), 4.06 (s, 2H), 3.00 (s, 3H). HRMS (M−H) calcd for C20H15N2Cl4O3: 470.9836. found: 470.9832.
