実験手順

A solution of 0.9 g of (RS)-3-[5-(1,4-dioxa-spiro[4,5]dec-7-en-8-yl)-pyridin-2-yl]-5-methoxymethyl-oxazolidin-2-one and 0.4 g of palladium-on-charcoal (10%) in 150 ml of methanol was hydrogenated at room temperature and normal pressure. After filtering off the catalyst the filtrate was concentrated and the residue was recrystallized from diethyl ether. There was obtained 0.35 g of (RS)-3-[5-(1,4-dioxa-spiro[4,5]decan-8-yl)-pyridin-2-yl]-5-methoxymethyl-oxazolidin-2-one. M.p.: 117°-121°.
