Participants

Reaction Steps

Allyl bromide (0.10 ml) was added to a suspension of 1-methyl-1-methoxy-3-(4-trifluoromethyl-3-pyridylcarbonyl)urea (0.25 g) and potassium carbonate (0.16 g) in N,N-dimethylformamide at 20° C., and stirred for 2 hours. Ethyl acetate and water were added and the organic phase dried (magnesium sulfate), evaporated and the residue purified by column chromatography on silica gel, eluting with n-hexane/ethyl acetate (2:1) to give 1-methyl-1-methoxy-3-allyl-3-(4-trifluoromethyl-3-pyridylcarbonyl)urea (0.26 g, Compound E-85).
