实验步骤: A solution of 3-Bromopropionic acid amide (0.075 g, 0.5 mmol) in THF (5 ml) was added to a solution of [4-(4-mercaptophenyl)butyl]carbamic acid tert-butyl ester 560 (0.13 g, 0.46 mmol) dissolved in THF (15 mL) and 4-methylmorpholine (NMM) (0.3 mL). The reaction mixture was stirred at 50° C. for 4 h and then cooled to room temperature. Two more equivalents of 3-bromoprionic acid amide (0.15 g, 1 mmol) were added. The mixture was further stirred at room temperature for 2 days.
