A mixture of 3-(1-methylindol-3-yl)-4-(3-aminophenyl)-1H-pyrrole-2,5-dione (100 mg, 0.32 mmol) and tetrahydro-4H-pyran-4-one (65 mg, 0.65 mmol) in MeOH (8 mL) was stirred at room temperature for 40 min., and then NaCNBH3 (63 mg, 1.0 mmol) was added. After stirring the reaction mixture overnight the volatiles were removed under vacuo and the residue was purified by preparatory TLC (3% MeOH/CH2Cl2) to give 3-(1-methylindol-3-yl)-4-(3-tetrahydropyran-4-ylaminophenyl)-1H-pyrrole-2,5-dione (88.2 mg, 70%). LC/MS: M+ 401(98.6%).
