The esterification of proline (I) with SOCl2 and ethanol gives ethyl prolinate (II), which by treatment with NH3 in methanol is converted into prolinamide (III). The acylation of (III) with cyclopropylcarbonyl chloride (IV) by means of K2CO3 in acetone yields 1-cyclopropylcarbonyl-2-carbamoylpyrrolidine (V), which is reduced with LiAlH4 in ether to afford 1-cyclopropylmethyl-2-aminomethylpyrrolidine (VI) (1,2). Finally this compound is condensed with ethyl 5-sulfamoyl-2-methoxybenzoate (VII) by heating at 120 C
