실험 절차

A solution of 200 g. of 2,6-dimethylaniline in 2 l. of ether is cooled in an ice bath and to this 88 g. of butyryl chloride in 150 ml. of ether is added dropwise (over 21/2 hours). A white precipitate forms and the reaction mixture is allowed to stir at 0° C. for 1 hour longer and then 15 hours at room temperature. The reaction mixture is then evaporated in vacuo and the white solid residue is slurried in 1 l. of water, filtered and washed with water and dried to obtain N-butyryl-2,6-dimethylaniline (m.p. 134°-6° C.).
