Participants

Reaction Steps

A solution of 4-(3-cyclopropyl-1,3-dioxoprop-1-yl)-2,2-difluoro-1,3-benzodioxole (12.0 g) in dry toluene was treated with N,N-dimethylformamide dimethyl acetal and the mixture stirred overnight. After evaporation in vacuo and re-evaporation after addition of toluene the residue was recrystal from cyclohexane-ethanol to give 4-(3-cyclopropyl-2-dimethylaminomethylene-1,3-dioxopropyl)-2,2-difluoro-1,3-benzodioxole (6.5 g) as a pale yellow solid, m.p. 118°-119° C.
