YieldReaction ConditionsOperation in experiment
93% With triethylamine; In dichloromethane; for 5.0h; To a solution of L-tryptophan methyl ester hydrochloride (0.500 mg, 0.002 mol.) in dichloromethane (10 mL) was added triethyl amine (3.0 mL) followed by trimethylsilylisocyanate (2.300 gm, 0.02 mol.). The reaction mixture was stirred at room temperature for 24 hr and then concentrated. The residue obtained was dissolved in AcOH (5 mL) and refluxed for 5 hr. The reaction mixture was extracted in ethyl acetate, washed with water, dried and concentrated. The residue was dissolved in EtOH and treated with KOH, and stirred for 30 min. Then the reaction was concentrated and dried under vacuum to give 5-(1H-indol-3-ylmethyl)-imidazolidine-2,4-dione potassium salt (245 mg, 46%). This solid (50 mg, 0.18 mg) was acidified with dilute HCl at 0 C. The residue was extracted in ethyl acetate, and concentrated. The solid obtained after concentration was dried under vacuum to give 893-19 (42 mg, 93%)

The mixture was heated to reflux for 7 hours, filtered and concentrated in vacuo to an oil. The concentrate and t-butylamine (10 ml) in 100 ml of anhydrous C2 H5 OH were heated to reflux for 3 hours and concentrated in vacuo. The free base crystallized in ether and was recrystallized from 2-propanol-petroleum ether.
