실험 절차

2-Benzyl-1-pyrroline (Example 1b, 85%, 74 g, 0.395 mol), dissolved in MeOH (360 ml), is treated with NaHCO3 (38 g, 0.45 mol), and the mixture is cooled to 5° C. A solution of chloroacetaldehyde (45% strength in water, 68 g, 0.4 mol), dissolved in MeOH (100 ml) is added dropwise to the solution at this temperature, and the mixture is stirred for 18 h with exclusion of light.
