실험 절차
Intermediate 53B (5.0 g, 15.5 mmol) was dissolved in DMA (40 mL) and 4-hydroxybenzaldehyde (2.17 g, 17.8 mmol) was added followed by Cs2CO3 (5.8 g, 17.8 mmol). The mixture was stirred at 110° C. for 5 h. Water was added and the mixture was extracted trice with DCM. The solution was filtered through a phase separator and the solvent was removed by evaporation. Ether was added to the residue and the formed solid was filtered and washed with ether. The product was dried in vacuo to give 3.58 g (66%) of 71A as a beige solid. 1H NMR (500 MHz, CDCl3): δ 4.37 (m, 1H), 4.70 (m, 1H), 4.79 (m, 1H), 5.18 (m, 2H), 6.91 (d, 2H), 7.53 (t, 2H), 7.60 (t, 1H), 7.87 (d, 2H), 8.16 (d, 2H), 9.92 (s, 1H).
