Reaction Steps

A solution of 530 mg 5-(4-chloro-phenyl)-2,2-dimethyl-5-prop-2-ynyl-(1,3)dioxolan-4-one in 10 ml tetrahydrofurane and 5 ml methanol is treated with 2 ml of 1N NaOH and heated at 60° C. for 1 hour. Then the solution is cooled down, diluted with water and washed with ether. Then the aqueous solution is acidified with 1N HCl and extracted with ethyl acetate. The extracts are dried over sodium sulfate and evaporated to obtain the 2-(4-chlorophenyl)-2-hydroxy-pent-4-ynoic acid of a brownish thick oil which is used for the next step.
