Reaction Steps

26.18 g Sodium triacetoxyborohydride are added at 5° C. to a solution of 10.0 g 4-methyl-3-oxo-piperazine, 13.51 g 1,4-dioxa-spiro[4,5]decan-8-one, 5.65 ml acetic acid and 200 ml dichloromethane. After 23 hours stirring at ambient temperature 100 ml dichloromethane and 100 ml 4N sodium hydroxide solution are added. The phases are separated and the organic phase is evaporated down. The residue is purified by chromatography.
