Reaction Steps

The compound prepared in Example 235 (0.14 g) was dissolved in dichloromethane (2 mL) and trifluoroacetic acid (0.4 mL). The reaction was stirred for 1 hour and then concentrated and pumped to dryness. The amine salt was dissolved in tetrahydrofuran (5 mL) and Macroporous triethylammonium methylpolystyrene carbonate (MP-carbonate: Argonaut Technologies catalog number 80,026-9; 0.65 g) (2.5-3.5 mmol/g) 1.6-2.2 mmol was added. After 2 hours of stirring the reaction was filtered, washed with tetrahydrofuran, concentrated and used without further purification.
