Title: Alkamine alkyl esters of 1-alkylpyrrole-3,4-dicarboxylic acids
IPC: C07D207/34
Filed: 1944-06-27
Abstract: Mixed alkyl-alkamine esters of pyrrole-dicarboxylic acids, of the general formula <FORM:0594698/IV/1> (wherein Alk represents an alkyl group, R1, R2, R3 and R4 represent alkyl groups of not more than 6 carbon atoms, and n is a positive integer not greater than 6), are manufactured by (a) treating a 1 : 2 : 5-trialkyl-3-carbalkoxypyrrole-4-carboxylic acid with thionyl chloride and esterifying the resulting acid chloride with a dialkylaminoalcohol, or by (b) reacting a dialkyl 1 : 2 : 5-trialkylpyrrole-3 : 4-dicarboxylate, in the presence of a catalytic amount of an alkali metal alcoholate, with an amount of a dialkylaminoalcohol so restricted (usually to less than 6 molecular proportions) as to form substantially the monoalkamine ester.  The starting materials for method (a) are themselves obtainable from the dialkyl esters by hydrolysis, transformation of the free acid into its anhydride and reacting this with an alkanol to produce a monoalkyl ester, whilst the initial dialkyl esters may be prepared as described in Specification 594,697.  The products are useful as activators for rubber accelerators, and some of them as local an sthetics, preferably in the form of their salts, e.g. the hydrochlorides.  In examples: (1) 1 mol. of diethyl 1 : 2 : 5-trimethylpyrrole-3 : 4-dicarboxylate (obtainable by condensing diacetosuccinate with methylamine) is heated with about 6 mols. of b -diethylaminoethanol in which a small amount of sodium has been dissolved, and the product is treated with hydrogen chloride in ether to precipitate the hydrochloride; (2) 1 : 2 : 5-trimethylpyrrole-3 : 4-dicarboxylic acid anhydride (obtained by treating the free acid with acetic anhydride) is refluxed with ethyl alcohol and pyridine, and the resulting monoethyl ester is treated with thionyl chloride, the product warmed with b -diethylaminoethanol in benzene, and the resulting ester converted into its hydrochloride as in (1); (3) the b -diethylaminoethanol in (2) is replaced by g -diethylaminobutanol; (4) diethyl 1-n-myristyl-2 : 5-dimethylpyrrole-3 : 4-dicarboxylate (obtainable by condensing diethyl diacetosuccinate with n-myristylamine in glacial acetic acid) is treated as in (1), except that 10 mols. of b -diethylaminoethanol are used in this anomalous case.
