Versuchsvorschrift

To a stirred solution of 2′-chloro-9′-cyclohexyl-8′,9′-dihydrospiro[cyclopropane-1,7′-pyrimido[5,4-b][1,4]diazepin]-6′(5′H)-one (Intermediate 271; 849 mg, 2.767 mmol) in DMA (60 mL) under nitrogen was added methyl iodide (190 μL, 3.044 mmol). The mixture was cooled on an ice/water bath and sodium hydride (60% mineral oil dispersion; 122 mg, 3.044 mmol) added in one portion. The reaction mixture was stirred on the ice/water bath for 1 hour, the cooling bath removed and allowed it to warm to room temperature. After 1.5 hours the solvent was evaporated and the residue treated with an excess of water. This afforded a solid, which was filtered off and washed well with water and then dried by dessication under high vacuum over P2O5 overnight. To yield the title compound as an off-white solid (887 mg, 100%)
