Reaction Steps

A mixture of 2.4 g (8.0 mmol) of the compound from Step B, 1.8 g (10.1 mmol) tert.-butyl 4-chlorobutanoate (prepared according to Chem. Ber. 1965, 98, 2312), 2.8 g (20.3 mmol) dry potassium carbonate, and a catalytic amount potassium iodide in 50 ml dry DMF was heated at 100° C. for 6 h until the conversion was complete. It was poured into ice-cold water, and the crude solid title compound was collected by filtration. It was redissolved in hot ethyl acetate and dried over sodium sulfate, which was removed by filtration. The title hydantoin crystallized from the filtrate by addition of hexane.
