1-Acetylpiperazine → 7-[3-(4-acetylpiperazin-1-yl)propoxy]-4-(1H-indol-5-yloxy)-6-methoxyquinazoline

Participants

Reaction Steps

A mixture of 7-(3-bromopropoxy)-4-(1H-indol-5-yloxy)-6-methoxyquinazoline (200 mg, 0.47 mmol), (WO 00/47212 A1, Example 314), and 1-acetylpiperazine (180 mg, 1.40 mmol) in N,N-dimethylformamide (4 ml) was stirred at ambient temperature for 3 hours. The mixture was diluted with ethyl acetate and washed with brine (×2), dried (MgSO4) and concentrated under reduced pressure. Column chromatography of the residue (5% methanol/dichloromethane) gave 7-[3-(4-acetylpiperazin-1-yl)propoxy]-4-(1H-indol-5-yloxy)-6-methoxyquinazoline (109 mg, 49%) as a white solid.
