実験手順

To a mixture of (2S,3S,5S)-3-(methoxycarbonyl)-5-[(pyrrolidin-1-ylcarbonyl)oxy]piperidine-2-carboxylic acid (90.1 mg, 0.000300 mol) and 4-phenyl-1,2,3,6-tetrahydropyridine (64.6 mg, 0.000330 mol) HCl salt, benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (146 mg, 0.000330 mol) in N,N-dimethylformamide (0.44 mL, 0.0057 mol) was added N,N-diisopropylethylamine (0.115 mL, 0.000660 mol) at rt. The mixture was stirred at rt overnight, then quenched with aq. sodium bicarbonate. After separation of the organic layers, the aq. layer was extracted with EtOAc. The combined organic layers were washed with brine, dried, and concentrated to dry. The crude material was used directly in next step.
