Acetic acid, 2-(1,4-dioxaspiro(4.5)dec-8-ylidene)-, ethyl ester → Ethyl 2-(1,4-dioxaspiro[4.5]decan-8-yl)acetate

Participants

Reaction Steps

(1,4-Dioxa-spiro[4.5]dec-8-ylidene)-acetic acid ethyl ester (1.10 g, 4.86 mmol) was dissolved in 30 ml ethyl acetate and stirred with 110 mg Pd/C 10% under hydrogen atmosphere for 4 hours. The catalyst was filtered off and the solvent evaporated. The crude product (1.08 g, 97%) [MS: m/e=229.3 (M+H+)] was obtained as a colourless liquid and used without any further purification for the next step.
