Reaction Steps
A mixture of 3-(thiophene-2-carbonyl)amino-L-alanine on Wang resin (2.00 g) and 1-[[2-chloro-4-(tributylstannyl)benzoyl]oxy]-2,5-pyrrolidinedione (Example 374; 2.50 g, 4.6 mmol) in N,N-dimethylformamide was shaken for 72 h. The resin was washed with dichloromethane and methanol to give N-[2-chloro-4-(tri-n-butylstannyl)benzoyl]-3-(thiophene-2-carbonyl)amino-L-alanine on Wang resin.
