Procedure

Potassium carbonate (21 g, 152 mmol) was added to a mixture of 4-hydroxycinnamic acid 40.1 (6.25 g, 38.1 mmol) and p-methoxy benzyl chloride (10.35 mL, 76 mmol) in DMF (100 mL). The mixture was stirred at 80° C. for five hours. After cooling, the mixture was poured into water (700 mL). The solid was collected by filtration, washed with water and dried to give 40.2 (15 g). MS ESI (pos.) m/e: 405 (M+H). 1HNMR (CDCl3) δ 7.68 (d, 1H), 7.47 (d, 2H), 7.38 (m, 4H), 6.95 (m, 6H), 6.35 (d, 1H), 5.20 (s, 2H), 5.03 (s, 2H), 3.84 (s, 3H), 3.83 (s, 3H).
