Benzene → HCID 9889686, compound

Participants

Reaction Steps

A solution of the product from step (d) (4.5 g) in THF (50 ml) was stirred at room temperature and heptyl isocyanate (5.5 g containing 36 mole % benzene, prepared by the method described in Organic Syntheses, Collective Volume 3, p. 846) and N,N-dimethylaminopyridine (750 mg) were added. The mixture was stirred at room temperature for ca 60 hours, then evaporated under reduced pressure to give an oil which was flash chromatographed through a silica column using ether/hexane (2:1 v/v). The eluate was evaporated under reduced pressure and the residue crystallised from hexane and triturated with methanol to give 4.5 g of material. The latter was flash chromatographed through a silica column using ether/hexane (2:1 v/v) and then freeze-dried from dioxan to give 5.3 g of the desired product, mp 105°-107° C.
