CODEN: GWXXBX. CLASS: IC: C07C143-80.Several substances with their cas registry numbers 62793-68-4 and 7057-68-3 may be metioned in this study. PRIORITY: CH 75-11366 2 Sep 1975. DOCUMENT TYPE: Patent CA Section: 25 (Noncondensed Aromatic Compounds) The title compds. I (R, R1 = H, Me, Bu, Ph, etc.; R2 = H, Cl; R3 = H, Me, Et; RR1N = piperidino, morpholino) were prepd. from a sulfonyl chloride and an amine. Thus, II reacted with Me2NH on PhMe to give I (R = R1-R3 = Me, R2 = 4-Cl). About 40 I were prepd. for treatment of allergic diseases (no data). .
