| titleOfInvention | PROCEDURE TO PREPARE ESTERS OF ACETYLSALICILIC ACID. |
| abstract | Procedure for preparing esters of acetylsalicylic acid, of general formula **(See formula)** where n represents an integer at least equal to 2 and at most equal to 5 when A represents a cyano residue, and represents an integer at least equal to 1 and at most equal to 5 in all other cases; A is either an alkoxycarbonyl residue (see formula), where E is a straight or branched chain alkyl radical containing from 1 to 6 carbon atoms; or it is a carbamoyl residue **(See formula)** wherein R1 and R2 are identical or different and represent either a hydrogen atom or a branched or straight-chain alkyl moiety containing 1 to 5 carbon atoms; R1 and R2 and the nitrogen atom as a whole may also form a heterocyclic radical, possibly containing one or more other heteroatoms, such as the piperidino, morpholino, triomorpholino radicals, etc., or a cyano radical or an acyl radical (see formula), where R is a straight or branched chain alkyl radical containing from 1 to 6 carbon atoms; characterized in that acetic anhydride is reacted with an acetic acid ester of the general formula **(See formula)** where n and A have the same meanings as above.
