To a solution of methyl 4-methylaminobenzoate (1.0 g, 6.05 mmol) in anhydrous pyridine (20 mL) was added dropwise hydrocinnamoyl chloride (1080 μL) at rt. After 16 hrs water (5 mL) was added and the resulting mixture was stirred for 1 hr at rt. The resulting mixture was poured into water (300 mL) and HCl (5 N, 50 mL) was added. The compound was extracted with AcOEt (2×300 mL) and washed with a saturated aqueous solution of NaHCO3 (150 mL). The combined organic layers were dried over MgSO4 and evaporated under vacuo to give the title compound (1.80 g) was obtained as a beige solid (95%) in 95.3% purity by HPLC (MaxPlot detection between 230 and 400 nm).
