Reaction Steps

To a solution of 69 (1.1 g, 5.0 mmol) in 50 ml of anhydrous THF are added LAH (400 mg, 10 mmol) and the mixture refluxed for 18 hours. The mixture is cooled to 0° C. and treated successively with 0.4 ml of water, 0.4 ml of 3N aq. sodium hydroxide, and 1.2 ml of water. The mixture is stirred for 15 min. and then extracted three times with DCM. The combined organic phases are dried over anhydrous sodium sulphate and evaporated. The residual yellow oil (880 mg) is purified by chromatography (Silica gel 60, 0.063-0.2 mesh, DCM/MeOH/conc. ammonia 90:9:1).
