Reaction Conditions

Reaction Steps

Under a dry nitrogen atmosphere, 0.5 g (0.0022 mole) of N,N,2-trimethyl-[1,1'-biphenyl]-3-methanamine was dissolved in 5.5 ml of dry toluene with stirring and the solution was heated to 80° C. A solution of 0.36 g (0.0033 mole) of ethyl chloroformate in 1.1 ml of dry toluene was added dropwise during 5 minutes. The reaction mixture was stirred for 3.3 hours at 80° C., then cooled to room temperature and filtered. The solvent was removed from the filtrate under reduced pressure to give 0.5 g (100% yield) of 3-chloromethyl-2-methyl-[1,1'-biphenyl] as a light orange oil.
