II-5-2: Synthesis of 4-n-undecylpyridine A mixture of 8.50 g (34 mmol) of 4-n-undecanoylpyridine, 5.55 g (0.11 mol) of hydrazine.monohydrate, 4.41 g (74 mmol) of potassium hydroxide, and 30 ml of triethylene glycol was heated at 110° to 125° C. for one hour, and further, at 180° to 185° C. for 4 hours. After cooling, 50 ml of water was added, and the mixture was extracted with diethyl ether, washed with water and then dried over anhydrous potassium carbonate. After concentration under a reduced pressure, the residue was purified by distillation under a reduced pressure to give 6.40 g of the desired product (yield 79.8%). bp2: 128° C. IR (film): 1595 cm-1.
