実験手順

The alkylation of 7-bromo-1-hydroxy-6-azaisoquinoline (1.00 g, 4.40 mmol) using 3-cyanobenzyl bromide (1.31 g, 6.69 mmol) and cesium carbonate (2.18 g, 6.69 mmol) in dimethylformamide is carried out as previously described in Example 1, Step (1). Purification on a silica gel column eluted with hexanes/ethyl acetate 3:1, followed by trituration with hexanes/ethyl acetate 4:1 will afford the desired product. Step (2): 3-[1-oxo-7-(3-Phenyl-prop-1-ynyl)-1H-6-azaisoquinolin-2-ylmethyl]benzonitrile

後処理
