Reaction Steps

N-hexyl DL-tartarimide was prepared by the reaction of n-hexyl amine with DL-tartaric acid. DL-Tartaric acid (10.026 g, 66.80 mmole) and toluene (17.327 g) were weighed into a 250 mL 3-necked round-bottomed flask equipped with a teflon-coated magnetic stir bar. A Claisen adapter was placed in the center neck, a Dean-Stark trap was placed on top of the Claisen adapter, and a condenser was placed in the neck of the Dean-Stark trap. A nitrogen inlet adapter was placed on the condenser. In the left neck was placed a pressure-equalizing addition funnel containing n-hexyl amine (6.760 g, 66.80 mmole) and toluene (7.936 g, added to ensure complete transfer of the amine). In the right neck was placed a rubber septum which held a thermocouple. The apparatus was purged with nitrogen for 10-15 minutes and then heated to ˜100° C.
