O-Acetyl-l-carnitine·Cl (1.000 g, 4.17 mmol) was dissolved in 12.5 mL of a mixture of DMF/dioxane/water (2:2:1). NHS (0.528 g, 4.59 mmol) and DCC (0.947 g, 4.59 mmol) were added and the mixture was stirred overnight at ambient temperature. Solvents were evaporated and the remaining residue was dried overnight in high vacuum. The crude succinimidyl ester intermediate was dissolved in 20 mL of anhydrous DMF. Amphetamine sulfate (0.700 g, 1.90 mmol) and NMM (0.92 mL, 8.34 mmol) were added and the mixture stirred overnight. Solvent was evaporated to dryness and the remaining residue was leached with IPA. Solvent was evaporated to yield Carn-d-amphetamine.
