Abstract Gefitinib was synthesized from 3-hydroxy-4-methoxybenzaldehyde via conversion of aldehyde to nitrile, condensation with N-(3-chloropropy1)morpholine, nitration and reduction to give 2-amino-4-methoxy-5-(3-morpholin-4-ylpropoxy)benzonitrile, which was subjected to amidination with 3-chloro-4-fluoroaniline and cyclization in the presence of formic acid with an overall yield of about 44％.
