- Lithiation leads to products of metallation at the 3- and 2-methyl groups in that order, whereas attack at the 5-methyl, surprisingly, is disfavored. For a detailed study of lithiation with LDA, see: J. Org. Chem., 48, 2130 (1983). For subsequent reaction with trans-1,2-dichloroethylene to give isomeric pyrrolo[1,2-a]pyrazines, see: J. Heterocycl. Chem., 18, 445 (1981).
