Reaction Steps

To a suspension of 2.03 g (10.7 mmol) of 1,2-dihydro-3-methyl-1,4,7b-triazacyclopent[cd]inden-2-thione in 50 ml of N,N-dimethylformamide were added 3.18 g (10.7 mmol) of N-(5-bromopentyl)phthalimide and 2.24 ml (16.1 mmol) of triethylamine. The mixture was stirred for two hours at 100° C. After cooling, the resulting precipitates were collected by filtration, washed with N,N-dimethylformamide, ethanol, and diethylether, successively, dried to afford 3.44 g of the desired compound (79.3%, a pale brown solid).
