To a solution of compound N-methyl-6-(1H-pyrrolo[2,3-b]pyridin-5-yl)-N-((tetrahydro-2H-pyran-4-yl)methyl)pyrazine-2-amine (143) (20 mg, 1.0 eq) in dichloromethane (5 mL) was added n-chlorosuccinamide (2.0 eq) and the resulting reaction mixture was stirred at room temperature overnight. After completion of the reaction the solvents were removed and extracted into CH2Cl2. The organic layer was separated and the aqueous phase was extracted with CH2Cl2 to retain the crude material. The combined organic layer was washed with brine solution and dried over sodium sulphate and the solvents were removed by rotary evaporator. The crude material was purified by flash column with 100-200 mesh silica gel employing 40% EtOAc/hexane eluents to obtain the pure off-white coloured solid of 6-(3-chloro-1H-pyrrolo[2,3-b]pyridin-5-yl)-N-methyl-N-((tetrahydro-2H-pyran-4-yl)methyl)pyrazin-2-amine compound 144.
