実験手順: 704 mg (1.24 mmol) of (4S)-3-oxo-8-[2-(8-tert-butoxycarbonyl-5,6,7,8-tetra-hydroimidazo[1,2-a]pyrimidin-2-yl)ethoxy]-2-(2,2,2-trifluoroethyl)-2,3,4,5-tetrahydro-1H-2-benzazepin-4-acetic acid obtained in Example 5-(a) and 1.30 mL (6.26 mmol) of 1-undecyl alcohol were mixed, 12.4 mL (49.6 mmol) of 4N hydrogen chloride/1,4-dioxane solution was added to the mixture, and the resulting mixture was stirred under nitrogen gas atmosphere at 45° C. for 4 hours.

実験手順: For example, 8.6 g (50 mmol) of 1-undecanol, 5 ml (1.07 eq.) n-propyl isocyanate and 50 ml diethyl ether were heated in a stainless steel bomb at 65° for 72 hours. Solvent and excess isocyanate were removed on a rotary evaporator and the residue was crystallized from hexane to give 11.5 g (89%) of 1-undecyl propylcarbamate, mp 45°-45.5°. Solvent and excess isocyanate were removed on a rotary evaporator the residue was crystallized from hexane

実験手順: Undecanol (14 g), 48% aqueous hydrobromic acid (30 g) and concentrated sulphuric acid (5 ml) are heated together under reflux for 51/2 hours. After cooling, water is added and the organic layer is separated, washed with concentrated sulphuric acid (20 ml), brine (50 ml) and dilute aqueous sodium carbonate (50 ml), and is then dried over calcium chloride. Distillaion under vacuum gives 1-bromoundecane (12 g) as a yellow oil, b.p. 60°-70° C./0.1 mm. under reflux for 51/2 hours After cooling the organic layer is separated washed with concentrated sulphuric acid (20 ml), brine (50 ml) and dilute aqueous sodium carbonate (50 ml) is then dried over calcium chloride

実験手順: Another synthesis starts from n-undecanol, which is reacted with methanol in the presence of sodium methylate. 2-methyl-undecanol is formed, which is then dehydrogenated to form the aldehyde. (Chemical Abstracts Vol. 74 [1971], 12552 X.)
