7.5 mg | With water; trifluoroacetic acid; In dichloromethane; at 25℃; for 0.5h; | General procedure: 50 mumols of resin 1 was treated with 100 mumols of 0.20 M BTPP in NMP followed by 100 mumols of 0.20 M fluorinated benzyl bromide R1X in NMP. After two days the reaction mixture was filtered and the resulting resin 2 was washed once with 3 mL of THF. To the resin was then added 2.5 mL of 1.0 N HCl in THF (1:2). After 20 minutes the resin was filtered and was washed with 3 mL of THF followed by 2×2.5 mL of 0.20 M diisopropylethylamine in NMP, 2×2.5 mL of NMP, 3×2 mL of THF and 3×3 mL of dichloromethane to give resin 3. Treatment of resin 3 with 2 mL of 35:60:5 TFA/DCM/H2O for 30 minutes was followed by filtering and washing the resin with 2 mL of 35:60:5 TFA/DCM/H2O and 2 mL of DCM. The combined filtrates were evaporated to a residue which was chromatographed on silica gel using iPrOH/MeOH/NH4OH mobile phases to elute the free bases 4. |
