Reaction Steps

Substantially the same procedure as in Example 1 was repeated using 3',4',5'-trimethoxyacetophenone (659 mg) and 6-methoxyindole-3-carboxaldehyde (550 mg) except that the reaction solution was concentrated under reduced pressure, that the residue was purified by silica gel column chromatography, and that the obtained crude crystals were recrystallized from ethanol, to give Compound 39 (369 mg).
