Method 20 Synthesis of 3-[1-(4-iodophenyl)-1,2-dimethyl-propyl]-1-[2-(4-methylpiperazin-1-yl)ethyl]indole (Intermediate 26) To a solution of I-11 (150 mg, 0.39 mmol) in anhydrous DMF (4.5 mL) is added NaH (60percent dispersion in mineral oil) (18 mg, 0.46 mmol). The mixture is stirred at room temperature for 10 minutes and then methanesulfonyl chloride (0.032 mL, 0.42 mmol) is added and stifling continued for 18 h. The reaction is retreated with more methane sulfonyl chloride (0.03 mL) and NaH (60percent dispersion in mineral oil) (18 mg) and stirring is continued for another 2 h before quenching with water. The reaction is partitioned between saturated aqueous NaHCO3 and DCM. The combined organics are washed with brine, dried over anhydrous Na2SO4, and concentrated in vacuo to give I-25 (193 mg). To a solution of 1-(2-hydroxyethyl)-4-methylpiperazine (54 mg, 0.37 mmol) in toluene (3 mL) is added NaH (60percent dispersion in mineral oil) (18 mg, 0.45 mmol) and the suspension stirred at room temperature for 10 min. A solution of I-25 (175 mg, 0.37 mmol) in toluene (1.5 mL) is added and the reaction heated to 110¡ã C. for 3 h. A further 1 eq of 1-(2-hydroxyethyl)-4-methylpiperazine and 1.2 eq of NaH are added and heating continued for 3 h. The reaction is quenched by dropwise addition of water and extracted with DCM. The combined organics are washed with water and brine, and dried over anhydrous Na2SO4. The solvent is removed in vacuo and the crude material purified by flash chromatography (SiO2, 2percent MeOH in DCM) to give the title intermediate I-26 (52 mg) m/z 516.1 [M+H].
