Versuchsvorschrift

The alkylation of 7-bromo-3-hydroxy-8-azaisoquinoline (1.00 g, 4.46 mmol) using methyl 4-(bromomethyl)benzoate (1.53 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). The solid is crystallized from hexanes/ethyl acetate 2:1, the white crystals collected by filtration and dried to give the desired product.
