Versuchsvorschrift

Commercially available (+/−)-2-amino-2-methyl-pentanedioic acid (1.00 g, 6.8 mmol) was dissolved in 10 mL boiling water and treated portionwise with potassium cyanate (1.20 g, 14.8 mmol). After 15 min, 10% aq HCl (15 mL) was added and the reaction refluxed for 30 min after which the solvent was evaporated off and the white solid filtered, washed with cold water, and dried to give 870 mg (75%) of hydantoin derivative. MS found:(M+H)+=173. (103b) 5-methylhydantoin-5-acetic acid (50 mg, 0.30 mmol) and 4-[(2-methyl-4-quinolinyl)methoxy]-aniline bis-HCl salt (101 mg, 0.30 mmol) were coupled using general coupling method A to give 20 mg (13%) of the product hydantoin. MS found:(M+H)+=419.
