Chloroacetyl chloride → N-(2'-Chloro-6'-methylphenyl)-N-chloroacetyl-4-methylaniline

関与物質

反応手順

The solution of N-(2′-chloro-6′-methylphenyl)-4-methylaniline (1.4 g) in 2.21 g chloroacetylchloride is heated to 90° C. for 4 h. The mixture is diluted with toluene (25 ml), cooled to room temperature and washed with aqu. sodium carbonate. The organic phase is dried, evaporated and the residue is subjected to flash chromatography [57 g silica, toluene and toluene/ethylacetate (98:2)] to afford 1.45 g of N-(2′-Chloro-6′-methylphenyl)-N-chloroacetyl-4-methylaniline which is crystallised from heptane, mp: 113-114° C.
