Abstract
NEW MATERIAL:Acylated pyrrole derivatives of formula I (R1 is lower alkyl; R2 is H or lower alkyl; R3 is H or 2 - 10C acyl; Ar is 5 or 6 membered monoaromatic ring).
EXAMPLE: 2-]3-Benzoyl-2,5-dimethylpyrrole-1]-1-propanol.
USE: Analgesics, antiflammatory agents, antithrombotic agents, and antiarteriosclerosis.
PREPARATION: The condensation reaction of a pyrrole derivative of formula II (R31 is H or 2 - 10C acyl) with an acylating agent selected from the groups consisting of aromatic carboxylic acids, acid halides and anhydrides is effected in the presence of an acidic catalyst as sulfuric or Lewis acid, when necessary, followed by hydrolysis to prepare an acylated pyrrole of formula I.
