Hydrazine hydrate (1:1) → HCID 12814340, compound

Participants

Reaction Steps

18.3 g of tert-butyloxycarbonyl-L-phenylalanyl-L-serine methyl ester were dissolved in 50 ml of methyl alcohol, and to this solution 7.5 ml of 80% hydrazine mono hydrate were added. The mixture was stirred for 15 hours at room temperature and then the reaction mixture was concentrated under reduced pressure to give a solid substance. The solid substance was allowed to re-crystallization with ethyl alcohol and thereby tert-butyloxycarbonyl-L-phenylalanyl-L-serine hydrazide was obtained.
