The mixture was filtered and the filtrate evaporated in vacuo. The residue was purified by silica gel chromatographyusing gradient elution with dichloromethane/methanolic ammonia (7M) (100/0 to 90/10) to give (2S)-7-(2-hydroxy-3-(pyrrolidin-1-yl)propoxy)-6-methoxy-4-(2-methylindol-5-yloxy)quinazoline (106 mg, 36%).
