실험 절차

A mixture of 2-ethyl-4-formylimidazole attached to 2-chlorotrityl resin (4, 78 mg, 0.052 mmol based on 0.67 mmol/g loading), DMF (0.9 ml) and piperidine (0.1 ml) was gently stirred for 45 min. at ambient temperature, afterwhich was added 2-indolinone (5, 70 mg, 0.523 mmol). The resultant mixture was gently stirred and heated at 80° C. for 20 h. The resin was filtered and washed with 30 ml each of acetone, water, dichloromethane, methanol, and another portion of acetone. Finally, the resin was air dried for 20 min.
