<p>Title cpds. are of formula (I): where Q = CONR2R3; R' = H or 1-3C alkyl; R2 and R3 = H, 1-6C alkyl, 2-6C hydroxyalkyl, 4-7C dialkylamino-alkyl, or 7-9C aralkyl, or NR2R3 forms a is not >10C cyclic residue opt. contng. O or NR, where R = 1-4C alkyl or hydroxyalkyl; and rings A and B are opt subst. by F, Cl, Br, 1-6C alkyl, 1-6C alkoxy, CF3 or NO2; and include salts and 5-N-oxides of I. I are prepd. (a) by condensing HNR3R2 with a deriv. of I (Q = CO2H) or (reductively) with I (Q = CHO), or (b) by cyclizing a 2-(1H-1,2,4-1-rinzolo-3-carboxylic amide-5-halomethyl) substd. benzophenone, or other suitable deriv.</p> |
