実験手順

A solution of Compound 2 (2.5 g, 10 mmol) in chloroform (15 ml) was added drop wise to a solution of piperidine (1.7 g, 20.0 mmol) in chloroform (10 ml). The combined mixture was stirred at room temperature for 1 hour. The reaction mixture was then washed with water (2×, 50 ml) and brine (1×, 50 ml). The organic layer was dried with sodium sulfate and evaporated. The sticky white solid thus obtained was dissolved in ca. 5 ml of hot ethyl acetate and this solution was then slowly added to 40 ml hexane. The white solid that precipitated was collected, washed with hexane and dried to yield 2.2 g (74%) of Compound 3, Rf=0.28 (30% ethyl acetate in hexane). The structure of Compound 3 is given below:
