Versuchsvorschrift
Using an analogous procedure to that described in Example 5, 6-bromo-4-[3-methyl-4-(2-pyridylmethoxy)anilino]quinazoline dihydrochloride salt was reacted with di-isopropyl 2-thienylboronate to give 4-[3-methyl-4-(2-pyridylmethoxy)anilino]-6-(2-thienyl)-quinazoline in 70% yield, m.p. 205°-206° C.;
