piperazin-1-yl(pyrrolidin-1-yl)methanone

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: (2E)-4-Bromobut-2-enoic acid (106 mg, 0.64 mmol) and piperazin-1-yl(pyrrolidin-1-yl)methanone (125 mg, 0.68 mmol) were dissolved in DCM (5.0 mL), and DIPEA (111 mg, 0.85 mmol) was added. The mixture was stirred at rt for 2 h. Subsequently, the compound from Example 15A (150 mg, 0.43 mmol), DIPEA (55 mg, 0.43 mmol) and EDCI (82 mg, 0.43 mmol) were added. The reaction was stirred at 50° C. overnight. Then, water was added, and the mixture was extracted three times with DCM. The combined organic layers were dried over sodium sulfate. The solvent was removed in vacuo, and the residue was purified by preparative HPLC to yield 25 mg (10%) of the title compound. The reaction was stirred at 50° C. overnight the mixture was extracted three times with DCM The combined organic layers were dried over sodium sulfate The solvent was removed in vacuo the residue was purified by preparative HPLC
