Reaktionsschritte

One hundred mg of a cannabinol derivative having the formula ##STR3## were dissolved in 20 ml of 30% methanol at pH 4.5. To this solution, 84 mg of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride were added and the pH was adjusted to 4.5. After mixing at room temperature for 30 minutes, 100 mg of methylated bovine serum albumin were added in 20 ml of water with mixing, and the pH was again adjusted to 4.5. The solution was mixed for 1 hour at room temperature and then overnight at 4° C., after which any unconjugated cannabinol derivative was removed by dialysis against 1000-ml volume changes of sodium phosphate buffer at 4° C., to produce a THC-methylated albumin conjugate.
