実験手順: A stirred solution of 1-(4-methoxybenzyl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrrolo[2,3-b]pyridine (147PG) (50 mg, 0.137 mmol) and 1-(4-bromobenzyl)-4-methylpiperazine (121) (37 mg, 0.137 mmol, 1.1 eq) in DME (10 mL) was degassed and purged with N2 for 10 min and Cs2CO3 (2.0 eq) was added and the reaction mixture purged and degassed again. To this reaction mixture was added Pd(PPh3)4 (0.04 eq) and the resulting reaction was heated at 90° C. for 12 hrs in sealed tube condition. After completion of the reaction the contents were was cooled and diluted with CH2Cl2 and filtered through Celite bed. The CH2Cl2 layer was completely distilled off to get the crude product. The crude was passed through 100-200 mesh silica gel, eluting the pure compound 1-(4-methoxybenzyl)-5-(3-((4-methylpiperazin-1-yl)methyl)phenyl)-1H-pyrrolo[2,3-b]pyridine 151 obtained with 5% MeOH in CH2Cl2 as an off-white coloured solid in 30 mg quantity. purged with N2 for 10 min the reaction mixture purged degassed again the resulting reaction After completion of the reaction the contents were was cooled filtered through Celite bed The CH2Cl2 layer was completely distilled off to get the crude product eluting the pure compound 1-(4-methoxybenzyl)-5-(3-((4-methylpiperazin-1-yl)methyl)phenyl)-1H-pyrrolo[2,3-b]pyridine 151 obtained with 5% MeOH in CH2Cl2 as an off-white coloured solid in 30 mg quantity
