9.0 g (75%) 1 : Synthesis of D-lysergic Acid Diethylamide (I) Example 1 Synthesis of D-lysergic Acid Diethylamide (I) A mixture of 10.0 g (0.037 mol) of d-lysergic acid in 500 ml of dry dimethyl formamide (DMF), under argon, was treated with 9.0 g of carbonyl diimidazole and stirred at room temperature for 1 hour The reaction was then treated with 38 ml of diethylamine and stirred at room temperature overnight. The reaction was concentrated under reduced pressure. The residue was taken up in 500 ml of methylene chloride and washed with 500 ml of water. Insoluble material was removed by filtration and the layers were separated. The organic portion was washed with 250 ml of saturated brine solution, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was chromatographed on 800 g of silica gel using 3percent methanol in methylene chloride to yield 9.0 g (75percent) of d-lysergic acid diethylamide (LSD) as a light brown amorphous solid after evaporation of the solvents. in methanol, dichloromethane, water, N,N-dimethyl-formamide Patent; Ghoshal, Mitali; Vitone, Stephen; Sigler, Gerald F.; McNally, Alan J.; US2001/44118; (2001); (A1) English View in Reaxys

1 : Synthesis of D-lysergic acid diethyl amide 1 Example 1 Synthesis of D-lysergic acid diethyl amide 1 A mixture of 4.0 g (0.015 mol) of D-lysergic acid and 200 mL of dry DMF, under argon, was treated with 3.6 g (0.022 mol) of carbonyl diimidazole and stirred at room temperature for 1 hour. The reaction was treated with 15.2 mL (0.15 mol) of diethylamine and stirred at room temperature overnight. The reaction was concentrated at reduced pressure. The residue was taken up in 250 mL of CH2 Cl2 and washed with 250 mL of H2 O. Insoluble material was removed by filtration and the layers were separated. The organic portion was washed with 250 mL of saturated brine solution, dried over anhydrous Na2 SO4 and concentrated at reduced pressure. The residue was chromatographed on 500 g of silica gel using 3percent CH3 OH in CH2 Cl2 as eluent to yield 3.65 g (75.7percent) of D-LSD [α]D =+50.4° (c=1percent; CHCl3) as a light brown amorphous solid. The 8α-epimer (also known as iso-LSD) has [α]D =+226° (c=1percent; CHCl3). in dichloromethane, N,N-dimethyl-formamide Patent; Roche Diagnostics Corporation; US6063908; (2000); (A1) English View in Reaxys
