Alkylation of Theobromine: Preparation of Isopropyl and sec-butyl- theobromines using N, N-dimethylformamide as Solvent

N-isopropyltheobromine and N-sec-butyltheobromine were synthesized via nucleophilic substitution reaction by reacting theobromine and two kind of alkyl bromide derivatives, i.e. isopropyl bromide and sec-butyl bromide using N, Ndimethylformamide (DMF) as a solvent. Yields (N-isopropyltheobromine = 7.70%; N-sec-butyltheobromine = 5.89%) were slightly less than the previous synthesis which used e...
