Abstract
Methylation of the title compound (2-thiophenobarbital) under differen t conditions yielded two pairs of isomeric N-, and S--monomethyl and N ,N'- and N,S-dimethyl derivatives. Spectral data confirm their structu re and allow to identify the methyl substitution. Preliminary results of irradiation of N-CH3 substituted compounds are also presented.
