実験手順
To a stirred solution of 17.0 grams (0.067 mole) of 2,3-dichloro-N-(4-chlorophenyl)propanamide (Step A product) in 300 ml of toluene was added dropwise 11.3 grams (0.074 mole) of 1,8-diazabicyclo[5.4.0]-undec-7-ene in 100 ml of toluene. Upon completion of addition, the reaction mixture was stirred at ambient temperature for 60 hours. The reaction mixture was diluted with distilled water and transferred to a separatory funnel. The organic layer was separated and washed twice with water and twice with an aqueous solution saturated with sodium chloride. The organic layer was dried with magnesium sulfate and filtered. The filtrate was concentrated under reduced pressure to a residual solid. The solid was recrystallized from methylcyclohexane using silica gel as a decolorant to give 7.4 grams of 2-chloro-N-(4-chlorophenyl)-2-propenamide; mp 105°-106.5°.
