反応手順

3-Methoxy-4-hydroxyphenylacetic acid propyl ester (15-A) was dissolved in acetone. To the solution, 2 equivalents of K2CO3 were added, followed by 1.2 equivalent of 2-chloro-N,N-diethylacetamide. Under vigorous stirring, the suspension was warmed to reflux (60° C.) for ˜15 hours. After cooling to room temperature the reaction mixture was filtered and the remaining solvent removed under reduced pressure, giving a 95% yield of a dark yellow oil. The oily product was purified by silica column chromatography to produce the title compound.
