実験手順
A solution of 2-(4-azidobutyl)-3-(2-cyanoethoxy) carbonyl-1,4-dihydro-5-methoxycarbonyl-6-methyl-4-(4-nitrophenyl)pyridine (1.38 g,. 2.95 mmol) in 10 ml acetone was treated with 15 ml 1N KOH solution at 0° C. for 1 hr. The acetone was removed in vacuo and the aqueous layer was acidified to pH=3 by 2N hydrochloric acid, the resulting yellow precipitate was collected by filtration, washed with 10 ml of cold water and dried in vacuo to yield 750 mg (61% yield) of 2-(4-azidobutyl)-1,4-dihydro-5-methoxycarbonyl-6-methyl-4-(4-nitrophenyl) pyridine-3-carboxylic acid as a yellow powder.
