Versuchsvorschrift

A mixture of 2-chloro-6,7-dimethoxy-3H-quinazolin-4-one 1b, (0.77 g, 3.23 mmol), 5-(4-methyl-piperazine-1-sulfonyl)-1,2,3,4-tetrahydro-isoquinoline 11a (1.25 g, 3.41 mmol) and triethylamine (0.75 g, 1.04 mL, 7.46 mmol) in DMSO (15 mL) was heated at 80° C. with stirring for 18 h. After cooling to room temperature the reaction was diluted with water. The precipitated white product was collected by filtration, washed with water, and dried to give 0.6 g of 6,7-dimethoxy-2-[5-(4-methyl-piperazine-1-sulfonyl)-3,4-dihydro-1H-isoquinolin-2-yl]-3H-quinazolin-4-one 401, mp. 230-237° C.
