반응 단계
A mixture of thiophene-2-carbaldehyde (Compound 66a) (1.20 g, 0.0107 mol), malonic acid (1.11 g, 0.0107 mol) and ammonium acetate (0.825 g, 0.0107 mol) in DMF (8.5 mL) was heated to 100° C. for 3 h. The system was diluted with ethyl acetate and washed with water and dried over MgSO4. The solvent was removed in vacuo and the title compound was purified by silica gel column chromatography using 3:1 Hexanes:ethyl acetate as the eluent.
