The alkylation of theobromine (I) with undecenyl mesylate (II) in the presence of NaH in DMSO afforded the 1-undecenyl xanthine (III). Dihydroxylation of the terminal double bond of (III) by means of N-methylmorpholine-N-oxide and a catalytic amount of potassium osmate gave diol (IV), which was further converted to bromo acetate (V) by treatment with a solution of HBr in AcOH. Methanolysis of the bromoester (V) with concomitant cyclization gave rise to epoxide (VI). Finally, epoxide opening upon heating with dodecylamine (VII) furnished the target amino alcohol.
