Abstract

Esters of (3a,16a)-eburnamenine 14-carboxylic acid are made by (a) reacting the potassium salt of the acid with an alkyl bromide in basic medium, in a phase transference reaction catalysed by tetrabutyl ammonium, in a mixt. of water, toluene and/or chloroform, for 3-24 hours at between 20 deg.C and b.pt.; (b) concentrating the organic phase; and (c) recrystallising the concentrate from organic solvent, to obtain the esters of formula (I); in which R is methyl isopropyl or other.
