3-[(3,4-Dichloro-benzyl-methyl-carbamoyl]-2-hydroxy-acrylic acid methyl ester (Compound 12-B) was treated with paraformaldehyde and N-propylamino imidazole as described in the preparation of Compound 12. The resulting residue was purified by chromatography (YMC Combiprep ODS-A, 30 mm×50 mm, MeOH/H2O/0.1% TFA) to yield the title compound as an amber foam (59.1 mg, 28% yield). 1H NMR (300 MHz, DMSO) δ: 14.47 (bs, 1H), 11.05 (bs, 1H), 9.10 (s, 1H), 7.82 (s, 1H), 7.70 (s, 1H), 7.62 (d, 1H, J=8.05), 7.52 (s, 1H), 7.25 (d, 1H, J=7.32), 4.59 (s, 2H), 4.19 (t, 1H, J=6.95), 4.09 (s, 2H), 3.41 (t, 2H, J=6.59), 2.98 (s, 3H), 2.13 (t, 2H, J=6.59). HRMS (M+H) calcd for C19H21N4Cl2O3: 423.0990. found: 423.0982.
