Procedure
DMF (3 lt), 6-(3-chloropropoxy)-7-methoxy-4-chloro quinazoline (200 gm) and morpholine (210 gm), were heated to 70-75° C. for 6-8 hours. The reaction mass was cooled to room temperature, and methylene chloride (2.5 lt) and water (2.5 lt) were charged. The layers separated and the aqueous layer extracted with methylene chloride twice (500 ml). The combined methylene chloride layer was washed with water, dried over sodium sulphate (10 gm) and concentrated completely at 35-40° C. to yield the title compound (200 gm, 85% yield).
