Procedure
A mixture of 131 mg of 3-amino-2-methylthio-3H-quinazolin-4-one as synthesized in above Step 6-1-A and 172 mg 3-(4-quinolin-2-ylpiperazin-1-yl)propylamine was heated at 145° C. under stirring for 5 hours. The reaction mixture was cooled and purified on silica gel column chromatography (methanol:methylene chloride=1:19) to provide 198 mg (73%) of 3-amino-2-[3-(4-quinolin-2-ylpiperazin-1-yl)propylamino]-3H-quinazolin-4-one.
