实验过程

N,N′-Di-iso-butyl DL-malamide was prepared by the reaction of iso-butylamine with diethyl DL-malate. To a round-bottomed flask were added diethyl DL-malate (5.229 g, 1 eq) and iso-butylamine (14.058 g, 7 eq). The clear light yellow solution was stirred for 24 hours at room temperature, after which point a white solid had precipitated from solution. The solid was filtered, washed with hexane (3×25 mL), and dried under vacuum (1.96 g, 29% yield). The product was >99% pure as determined by NMR analyses.
