实验过程

Sodium nitrite (1.3 g) in water (60 ml) was added over 25 minutes to a solution of 3-amino-2-[3-(5,6,7,8-tetrahydroquinol-8-yl)propylamino]-5-(pyrid-3-ylmethyl)pyridine (5.5 g) in molar sulphuric acid (250 ml) stirred at 4° C. The reaction mixture was stirred at 4° C. for 50 minutes, then allowed to warm to room temperature, basified with 10 molar sodium hydroxide solution to pH 13 and extracted with chloroform (3×150 ml). The chloroform extracts were combined, dried over magnesium sulphate, and the solvent removed to give a brown oil (6.04 g). The oil was chromatographed on silica in 5% MeOH/chloroform to give the title compound as an oil (3.61 g).
