Procedure
2-Oxoglutaric acid (1.46 g) and L-alanyl-L-proline (0.37 g) were treated with sodium cyanoborohydride (0.38 g) as described above. Crude N-(1,3-dicarboxypropyl)-L-alanyl-L-proline (0.47 g) was obtained, m.p. 140°-160°. The mass spectrum of silylated material showed an ion at 517 m/e equivalent to the molecular ion for the trisilylated derivative minus methyl (532-15). The nmr spectrum was consistent with structure. Methyl resonances were centered at 1.4 ppm.
