Reaction Steps

A mixture of 4-(4-adamantan-1-ylphenoxy)-2-(N-t-butoxycarbonyl-N-methylamino)nitrobenzene (14 g), palladium on carbon (1.50 g, 10%) and methanol (300 ml) was stirred at room temperature under a hydrogen atmosphere for 2 hours and then 50° C. for 2 hours, allowed to stand at room temperature overnight and then stirred at 50° C. for 2 hours. The insoluble material of the reaction mixture was filtered and the filtrate was concentrated under reduced pressure. The residue was chromatographed on a silica gel column using hexane:ethyl acetate=3:1 as the eluant to afford the title compound (6.70 g, mp 85-90° C.).
