Reaction Steps

3-Hydroxy-4-oxo-10-(2-piperazin-1-yl-ethyl)-4,10-dihydro-benzo[4,5]imidazo[1,2-a]pyrimidine-2-carboxylic acid, 3,4-dichloro-benzylamide (Example 15.5) (75 mg, 0.146 mmol) and triethylamine (60 μL, 0.31 mmol) were dissolved in dichloromethane (1 mL) and to this was added mesyl chloride (18 μL, 0.31 mmol). The reaction was stirred at room temperature for 15 minutes after which time the solvents were concentrated in vacuo and the residue purified by column chromatography (95:4.5:0.5 dichloromethane:methanol:aqueous ammonia) to afford the desired product (65 mg, 76%).
