This invention relates to derivatives of 3-propionylsalicylic acid represented by the formula (1) STR1 wherein R represents a hydrogen atom, a lower alkyl group or a group STR2 (wherein R1 and R2 represent a lower alkyl group or R1 and R2, when taken together with the nitrogen atom to which they are attached, may form a heterocyclic ring with or without an intervening hetero atom, and n is an integer of 1 to 4), and X represents a hydrogen atom or a halogen atom, R being the group STR3 when X is a hydrogen atom. This invention also relates to processes for preparing the same.
