実験手順
1-Benzylimidazolidine-2,4-dione (100 mg, 0.526 mmol) and 1-isocyanatohexane (80.3 mg, 0.63 mmol) and, if required, a catalytic amount of 4-dimethylaminopyridine were dissolved in 10 ml of toluene and 0.5 ml of pyridine and stirred at 115° C. for 6 h. Then a further 80 mg of 1-isocyanatohexane were added, and the mixture was stirred at 115° C. for a further 6 h. The reaction mixture was concentrated and the residue was taken up in ethyl acetate and H2O, and the org. phases were washed twice with water, concentrated and purified by preparative HPLC (PR18, acetonitrile/water 0.1% TFA). Yield: 11.3 mg (7%), M+H+:318.14.
