Coupling of amino ester (XLIV) with carboxylic acid (IX) by means of EDC and HOBt produced the corresponding amide ester (XLV). In a related procedure, the analogous amino methyl ester (XLVI) was coupled with acid chloride (XV) to yield amide (XLVII). The title compound was then obtained by hydrolysis of the ethyl ester (XLV) with LiOH or by NaOH hydrolysis of diester (XLVII).
