<p>Cpds. (I) (where R1 is H or R2; R2 is 1-4C alkyl, 3 or 4C alkenyl, or -alkynyl or CH2CH2(CH2)n Y;n is 0 or 1; Y is MeO, CN, Br or Cl, R1 and R2 together contain 2-8C; R3 is 1-3C alkyl or Ph, and both R3 contain less than 8C or together form -(CH2)2-O-(CH2)2- or (CH2)q and q is 4,5 or 6) are prepd. by reacting a 3,5-dinitro sulphanilamide with a sulphoxide in the presence of a dehydrating agent. Thus (I; R1=R2=Pr, R3 = Me) is prepd. from 3,5-dinitro-N,N-dipropyl sulphanilamide and DMSO.</p> |
