실험 절차

The p-toluenesulfonylhydrozone of glyoxylic acid chloride (5.16 g; 0.02 mol) was added to a solution of (2Z-3-(3,6-difluoro-2-methoxyphenyl)-2-propen-1-ol (3.6 g; 0.018 mol) in dry CH2Cl2 (50 ml) at −5 C, and N,N-dimethylaniline (2.5 ml; 0.02 mol) was added slowly. After stirring for 30 min at −5 C, Et3N (12 ml; 0.09 mol) was added slowly. The resulting mixture was stirred for 15 min at −5 C and then for 30 min at room temperature, whereupon water (˜50 ml) was added. The organic phase was separated washed with water, brine and concentrated in vacuo. Flash chromatography (silica, EA:Hex; 1:1.5) gave 3.86 g (80%) of product as a yellow solid.
