Then the cap was replaced with a newTeflon-lined solid cap. The reaction vial was moved to a preheatedreaction block. After stirring for 18 h at the indicatedtemperature, the reaction mixture was cooled to 25 C and concentrated. The residue was purified by flash column chromatography to provide the desired arylated product.<\/p>\n<p>The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking.
