introduction

4 '-trifluoromethyldiphenyl -4-formaldehyde can be used as an intermediate in pharmaceutical synthesis, can be prepared by the reaction of bromobenzaldehyde and p-trifluoromethylphenylboronic acid, and can be used to prepare compound 1-(4'-(trifluoromethyl)-[1,1 '-biphenyl]-4-yl) butyl-1-ol.

preparation

4.625g(25mmol) p-bromobenzaldehyde, 9.495g(50mmol) p-trifluoromethylphenylboronic acid, 1.445g(1.25mmol) tetrakis (triphenylphosphine) palladium, 13.8g(100mmol) potassium carbonate, 100mL ethylene glycol dimethyl ether and 15mL water are mixed, nitrogen is pumped and exhausted for three times, and the reaction is 110 degrees for 24 hours. After the reaction, dichloromethane was used for extraction, the organic phase was washed with water and saturated salt water, anhydrous magnesium sulfate was dried, and the product (3.878g) was separated by column chromatography with a yield of about 62%.
