PROCEDURE
实验过程
173 mg (0.31 mmol) of the compound from example 2A was dissolved in 10 ml dichloromethane. 128 mg (0.31 mmol) S-Trityl-L-cysteinylglycinamide, 53 μl (0.31 mmol) N,N-diisopropylethyl-amine and 116 mg (0.31 mmol) HATU were added. The reaction mixture was heated for 30 min in a sealed tube at 60° C. in a microwave synthesizer. From the reaction mixture the solvent was removed under reduced pressure. The raw product was purified by preparative RP-HPLC on a C18 column with a water methanol gradient from 9/1 to 1/9. The product-containing fractions were combined and concentrated to dryness under reduced pressure. This gave 57 mg (0.02 mmol, 18% of theory) of the desired product.
