反応手順

295 (60 mg, 0.22 mol), DIEA (0.08 mL, 0.44 mmol), and CDI (71 mg, 0.44 mmol) were suspended in DMF (2 mL) and stirred for 4 h at room temperature. N1,N1-Dimethylethane-1,2-diamine (77 mg, 0.87 mmol) was added, and the reaction mixture was stirred for another 3 h. The reaction mixture was quenched with water. The resulting precipitate was filtered, washed with MeOH and H2O, and dried under vacuum to produce provide 296 (61 mg, 81% yield) as a solid. LC-MS (M+H=345, obsd.=345).
