실험 절차

N-(3,4-Dichloro-benzyl)-2-(2,2-dimethyl-5-oxo-[1,3]dioxolan-4-ylidene)-N-methyl-acetamide (Compound 37-A) was treated with paraformaldehyde and β-alaninamide as described in the preparation of Compound 37. The title compound 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 powder (0.0158 g, 7% yield). 1H NMR (300 MHz, CDCl3) δ: 2.68 (t, J=5.9 Hz, 2H), 3.02 (s, 3H), 3.79 (d, J=5.9 Hz, 2H), 4.29 (s, 2H), 4.58 (s, 2H), 6.23 (s, 1H), 6.59 (s, 1H), 7.09 (dd, J=8.4 Hz, J=10.3 Hz, 1H), 7.34 (d, J=1.8 Hz, 1H), 7.42 (d, J=8.4 Hz, 1H). HRMS (M−H) calcd for C16H17N3Cl2O4: 384.05179. found: 384.0517.
