Procedure
To a solution of 10-methoxyharmalan (1 mmol) in pyridine (2 ml) is added acetic anhydride (1.1 eq) . After acid hydrolysis and extraction with ethyl acetate, the crude product is flash-chromatographed (eluent: EtOAc/pet. ether; 50/50). The 1-methylene-2-acetyl-6-methoxy-1,2,3,4-tetrahydro-β-carboline elutes off first.
