실험 절차

For example, the 2,5-pyridinedicarboxylic acid, 2-methyl ester, 5-t-butyl ester 15 is contacted with a molar excess of morpholine in an appropriate organic solvent, such as tetrahydrofuran. The reaction is typically conducted at a temperature range of from room temperature to reflux and for a period of time ranging from 5 hours to 3 days. The 6-(morpholine-4-carbonyl)nicotinic acid, t-butyl ester 16 is isolated from the reaction mixture by standard extractive methods as is known in the art and may be purified by crystallization.
