실험 절차

rac-N-(t-butoxycarbonyl)piperidine-3-carboxylic acid (Can. J. Physiol. Pharmacol. 57, 1979, 763) in THF was activated with chlorodimethoxytriazine and N-methyl-morpholine and then coupled with β-alanine benzyl ester p-toluenesulphonate (J. Org. Chem. 17, 1952, 1564) and N-methylmorpholine to give rac-N-[[1-(t-butoxycarbonyl)-3-piperidinyl]-carbonyl]-β-alanine benzyl ester, m.p. 57°-59° C.
