Abstract

PURPOSE: Commercially sold theqbromine derivatives having visodilating and erythrocyte deformation accelrating activities is prepared in high yield by the reaction of a salt of theobromine with an organic sulfonyloxy derivative of 6-hydroxy-2- hexanone.
CONSTITUTION: The reaction between an alkaline earth metal salt of theobromine of formula I and an organic sulfonyloxy derivative of 6-hydroxy-2-hexanone of formulaII (R is lower alkyl, substituted or unsubstituted phenyl) in a solvent gives 1-(5'-oxohecyl)-theobromine of formula III in 89% yield in an example. The compound of formula II is prepared from 6-hydroxy-2-hexanone and an organic sulfonyl cholride
