実験手順

0.1 g of [(RS) -4-methyl-2-[[(S)-3-methyl-1-(methylcarbamoyl)butyl]carbamoyl]pentyl][(2-phenylmaleimido)methyl]phosphinic acid methyl ester was dissolved in 1 ml of dichloromethane and 2 ml of trifluoroacetic acid were added. The mixture was stirred at room temperature for 2 hours and the solvent was then removed by evaporation. The residue was taken up in 30 ml of acetone/ dichloromethane (1:1) and the solution was evaporated to give 95 mg of [(RS)-4-methyl-2-[[(S)-3-methyl-1-(methylcarbamoyl) butyl]carbamoyl]pentyl][(2-phenylmaleimido)methyl]phosphinic acid in the form of a tan colored foam.
