Reaction Steps

8-Chloro[1,3]dioxolo[4,5-g]quinazoline (100 mg, 0.48 mmol), (WO 9749688), was dissolved in dimethylacetamide (2.5 ml). 5-Hydroxy-7-azaindole (71 mg, 0.53 mmol), (prepared as described for the starting material in Example 2), and potassium carbonate (73 mg, 0.53 mmol) were added and the mixture heated to 85° C. for 3 hours. The reaction mixture was cooled, filtered and concentrated. The resulting residue was purified by column chromatography eluting with methylene chloride/methanol (91/9) to yield 4-(7-azaindol-5-yloxy)-6,7-methylenedioxyquinazoline (92 mg, 63%).
