Reaction Conditions

Reaction Steps

A solution of 0.700 g of sodium carbonate in 8 ml of water was added to a solution of 0.700 g of the product of Step A in 1 ml of methanol and the mixture was stirred for 2 hours at 20° C. and was filtered. The filtrate was adjusted to a pH of 2 and was saturated with sodium chloride. The mixture was extracted with chloroform and the organic phase was evaporated to dryness. The residue was crystallized from isopropyl ether to obtain 0.095 g of 3-formyl-4-methyl-pent-3-ene-1-oic acid melting at 102° C.
