Procedure

A mixture of 6 parts of 2-amino-N-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]amino]-1-piperidinyl]ethyl]-5-(methylthio)benzamide, 1.78 parts of 1,1'-carbonylbis[1H-imidazole] and 90 parts of tetrahydrofuran was stirred and refluxed overnight. The reaction mixture was evaporated. The residue was crystallized from acetonitrile. The product was filtered off and dried, yielding 5.2 parts (85%) of 3-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]amino]-1-piperidinyl]ethyl]-6-(methylthio)-2,4(1H,3H)-quinazolinedione; mp. 238° C. (compound 126).
