Procedure

2-Acetamido-4-(4-octylphenyl)-2-hydroxymethylbutane-1,4-diol (21′) (0.73 g) is dissolved in methanol (10 ml). Thereto is added a solution of LiOH (0.86 g) in water (10 ml), and the mixture is refluxed under heating for 2 hr. The reaction mixture is cooled and extracted with ethyl acetate. The organic layer is washed with brine and dried over sodium sulfate. The solvent is distilled away and the mixture is purified by silica gel column chromatography to give the title compound (22) as a colorless and amorphous powder. The resulting Compound (22) has the same physico-chemical characteristics as indicated in Example 2.
