<p>Cpds. (I): (where R1 is H or R2, R2 is 1-4C alkyl, 3-4C alkenyl or alkynyl or CH2CH2(CH2)nY and n is 0 or 1 and Y is OMe, CN, Br or Cl provided R1 + R2 contain 2-8C, R3 is H or Me, R4 is Pr or NR4 R4 is aziridino, pyrrolidino, piperidino morpholino, hexa-hydroazepino, or piperazino opt. substd. by one or two alkyl gp. having a total of up to 3C) are prepd. by Mannich reaction from a sulphanilamide HCHO and HNR4R4. Thus (I, R1 = R2 = Pr, R3 = H, and NR4R4 is piperidino) is prepd. from 3,5-dinitro-N4,N4-dipropylsulphonamide, HCHO and piperidine.</p> |
