Triethylamine → ethyl 5-[5-[4-[(acetylimino)aminomethyl]phenoxy]pentyloxy]-2-[N,N-bis(1-methylethyl)carbamoyl]phenoxydimethylacetate

Participants

Reaction Steps

To a mixture of 0.85 g (1.4 mmol) of ethyl 5-[5-[4-(aminoiminomethyl)phenoxy]pentyloxy]-2-[N,N-bis(1-methylethyl)carbamoyl]phenoxydimethylacetate monohydrochloride in 10 ml of methylene chloride is added 0.39 g (2.8 mmol) of phenyl acetate and 1 ml of triethylamine. The mixture is stirred at room temperature for 2 days and then poured onto a silica gel column and eluted with 80% ethyl acetate/hexane, and then pure ethyl acetate to give ethyl 5-[5-[4-[(acetylimino)aminomethyl]phenoxy]pentyloxy]-2-[N,N-bis(1-methylethyl)carbamoyl]phenoxydimethylacetate as a foam; CHN calculated for C33H47N3O7.0.5H2O:
