Preparation of alpha-carbonyl guanidine compounds General procedure for solution-phase PyBroP coupling <n="24"/>Carboxylic acid (200-300 mg, 1 eq) and bromo-tris-pyrrolidino- phosphonium hexafluorophosphate (1.1 eq) were suspended in dichloromethane (5 ml_) and the mixture was stirred at 20 0C for 10 minutes. N1N- Diisopropylethylamine (7 eq) was added to the mixture and stirred for a further 10 minutes. Suitably-protected amine (derived from aspartic acid, 1.1 eq) was added and the reaction mixture was then stirred for 2 days at 20 0C. After this time the reaction solvent was removed in vacuo and the residue partitioned between hydrochloric acid (1M aqueous solution, 20 ml_) and ethyl acetate (20 ml_). The phases were separated and the aqueous phase extracted with ethyl acetate (3 x 20 ml_). The organic phases were combined and washed with brine (saturated, aqueous solution, 25 mL), dried over magnesium sulfate, filtered and the solvent removed in vacuo to afford the crude residue. |
