Procedure
The product is obtained analogously to the preparation of “A64” by reaction of 2-[2-amino-4-(1,3-dihydroisoindole-2-carbonyl)quinazolin-6-yl]benzenesulfonyl chloride and tert-butyl (2-aminoethyl)methylcarbamate. The resultant tert-butyl (2-{2-[2-amino-4-(1,3-dihydroisoindole-2-carbonyl)quinazolin-6-yl]benzenesulfonylamino}ethyl)methylcarbamate is treated directly with 1 M HCl in dioxane, causing the protecting group to be cleaved. The purification is carried out by means of preparative column chromatography.
