Participants

Reaction Steps

434 (20 mg, 0.04 mmol), and CDI (14 mg, 0.09 mmol) were suspended in DMF (1 mL), and stirred for 2 h. N,N-dimethylethane-1,2-diamine (8 mg, 0.09 mmol) was added, and the mixture was stirred overnight at room temperature. The reaction mixture was diluted with H2O. The resulting precipitate was filtered, washed with MeOH, and dried under vacuum to provide 435.
