Versuchsvorschrift
The procedure in Example 6 is followed but using methyl 2,2-dimethyl-6-[(4,6-diphenyl-2-pyridyl) oxy]hexanoate (5 g), potassium hydroxide pellets (1.1 g) and ethanol (100 cc). The reaction mixture is refluxed for 24 hours. The product is purified by chromatography under pressure on silica gel (30-60 mm; eluent: n-hexane-ethyl acetate 8-2), white crystals (m.p.=115° C.)
