실험 절차

A solution of the carbonate (2.0 g, 3.4 mmol) produced in Example 17 in 20 mL of anhydrous dimethylformamide was added dropwise under nitrogen to a solution of nonylamine (760 μl, 4.1 mmol) and triethylamine (2.4 mL, 17 mmol) in 20 mL of anhydrous dimethylformamide at ice bath temperature. After the addition the solution was stirred at ice bath temperature for 2 hrs and at room temperature overnight. The reaction was diluted with ethyl acetate, extracted five times with water, one time with 1N HCl, five times with saturated Na2CO3, dried (MgSO4) and the solvent removed under reduced pressure to give 1.94 g of an off-white solid. Recrystallization from diisopropyl ether gave 1.55 g (77%) of the title compound as a white crystalline solid, mp 89-91° C.
