Procedure

NBS (0.18 g, 1.0 mmol) was added to a solution of 6-[4-(4-Methyl-piperazin-1-yl)-phenyl]-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (0.23 g, 0.5 mmol) in CH2Cl2 (5.0 mL). After 2 hr, the solution was evaporated and washed with EtOAc, filtered, and concentrated to give the corresponding 2-Bromo-6-[4-(4-methyl-piperazin-1-yl)-phenyl]-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (0.23 g, 0.42 mmol) as brown solid in 85% yield.
