Reaction Steps

g. 2-Pyrazinyl-ethyl mercaptan was prepared by reacting vinylpyrazine [obtained by the method described in J.Org.Chem. 27, 1363 (1962)] and hydrolizing the resulting thiolic acid ester according to the method described in J.Org.Chem. 22, 980 (1957). The product has a b.p. of 56.5°-60° C./0.003 mm. Hg. (1) h. 2-Pyrazinyl-ethyl methyl sulfide was prepared by reacting vinylpyrazine [c.f. J.Org.Chem. 27, 1363 (1962)] with methylmercaptan by the action of ultra violet light and in the presence of benzoyl peroxide by the method described in Acta Chem. Scand. 8, 295 (1954). The product was identified by mass spectrometry. It has a b.p. of 57°-69° C. at 0.05 mm. Hg.
