실험 절차
Into a reactor were fed 6.2 g (31.6 m moles) of 1-(4,6-dimethoxypyrimidine-2-yl)-2-propanone, 4.8 g (31.5 m moles) of 2-methoxymethylphenylhydrazine, 4.76 g (34.9 m moles) of zinc chloride and 60 ml of toluene. Refluxing was made for 2 hours with heating. After the completion of the reaction, the reaction mixture was cooled to room temperature. Water and ethyl acetate were added and phase separation was made. The ethyl acetate layer was concentrated. The resulting crystals were washed with diisopropyl ether to obtain 4.57 g (14.6 m moles) of 3-(4,6-dimethoxypyrimidine-2-yl)-2-methyl-7-metoxymethylindole. Yield: 46%
