実験手順
To a suspension of 5-benzylidenebarbituric Acid (4 g) in 200 ml of methanol are added portionwise 1.4 g of sodium borohydride. After 10 minutes from the end of the addition, 100 ml of water are added and the mixture is acidified with 1 N hydrochloric acid to pH=2. The solvent is evaporated off and the aqueous phase is extracted with ethyl acetate. The pooled extracts are dried over sodium sulfate and concentrated to dryness. 3.6 g of the product crystallize, m.p. 207-209° C.
