Procedure

A mixture of the product of example 38 (35 mg, 0.14 mmol), K2CO3 (100 mg), and ethyl iodide (0.014 ml, 0.17 mmol) in acetone (5 ml) was stirred in a closed reaction tube at RT for 3 days. After concentrating the reaction, the residue was partitioned in ethyl acetate and water. The organic layer was dried (MgSO4) and concentrated to give crude product. The crude product was chromatographed (5% methanol in chloroform) on silica gel to give 8 mg of 7,9-dichloro-8-ethoxy-β-carboline.
