Procedure

3-Acetoxy-4-oxo-10-(2-piperazin-1-yl-ethyl)-4,10-dihydro-benzo[4,5]imidazo[1,2-α]pyrimidine-2-carboxylic acid methyl ester (Example 15.3) (97 mg, 0.235 mmol) was dissolved in Dichloromethane (1 mL) and to it was added diisopropylethylamine (95 μL, 0.52 mmol), followed by methoxymethyl chloride (20 μA, 0.258 mmol). The reaction was stirred at room temperature for 24 h before the solvents were evaporated and the residue purified by column chromatography (98:1.5:0.5 dichloromethane: methanol: aqueous ammonia) to afford the desired product (30 mg, 28%).
