Reaction Steps

A solution of 1-[1-(4-chlorophenyl)cyclobutyl]-3-hydroxy-3-methylbutan-1-one oxime (3 g prepared as described in Example 84 above) in dry tetrahydrofuran (20 ml) was added under nitrogen to lithium aluminium hydride (2 g). The mixture was heated under reflux for 3 hours and then left without further heating for 16 hours. Water (100 ml) was added dropwise and the organic layer was separated. The aqueous layer was extracted with ether and the extracts combined with the organic layer and dried. The solvents were evaporated to give an oil which was dissolved in ether. Addition of a solution of maleic acid in ether gave a gum which slowly solidified. The solid was added to an aqueous solution of sodium hydroxide and the mixture extracted with ether. Removal of the ether gave an oil which was purified by high performance liquid chromatography to give 4-amino-4-[1-(4-chlorophenyl)cyclobutyl]-2-methylbutan-2-ol (m.p. 60°-62° C. shrinks 50° C.).
