Reaction Steps

149 g of formic acid were added dropwise to 45.8 g of pyrrolidine, while cooling with ice. 181 g of 3-(2,4-dichlorophenyl)-2-methyl-2-propen-1-ylpropionaldehyde were then added, after which the mixture was heated at 100° C. for 12 hours and then evaporated down under reduced pressure. The residue was made alkaline with 25% strength NaOH and extracted with ether, and the organic phase was dried over KOH and evaporated down. Distillation of the residue gave 95 g of (X) of boiling point 130°-138° C./0.1 mbar.
