Versuchsvorschrift

To a suspension of 4-(phthalimidoacetyl)-2,3,3a,4,9,10a-hexahydrobenzo[b]cyclopenta[e][1,4]diazepin-10(1H)-one (389 mg, 1.0 mmol) in N,N-dimethylformamide (3 mL) was added sodium hydride (60% liquid paraffin dispersion, 44 mg, 1.1 mmol). The mixture was stirred for 10 minutes at room temperature. To this mixture was added 2-methoxybenzyl bromide (241 mg, 1.2 mmol), which was stirred for 90 minutes at room temperature. To the reaction mixture was added a saturated aqueous solution of ammonium chloride (3 mL), which was diluted with water. The resulting solid was collected by filtration, which dissolved in chloroform. The solution was dried over magnesium sulfate, which was subjected to filtration, and the filtrate was concentrated under reduced pressure. The concentrate was recrystallized from chloroform-ethanol to give 234 mg (yield 46%) of a mixture of cis-compound and trans-compound. m.p. 261°-272° C.
