Procedure

3,4-Dimethylaniline (5.20 g, 42.9 mmol) was dissolved in 150 mL of THF and treated with trans-cinnamoyl chloride (7.5 g, 45 mmol) with vigorous stirring at room temperature. After 2 hours the mixture was quenched with 10 mL of H2O and extracted with EtOAc (3×100 mL). The combined organics were washed with saturated solution of Na2CO3, brine, dried over MgSO4 and then concentrated in vacuo to yield the title compound as a pure white crystalline solid (6.2 g, 67%). MS (ES) m/e 252 [M+H]+.
