الإجراء التجريبي

To a suspension of 1.5 equiv of NaH in dry DMF (10 vols) at 0° C. was added a solution of tert-butyl(trans)-2-(1,1′-biphenyl-4-yl)cyclopropylcarbamate derivative (1 equiv) in dry DMF (2 vols) and stirr for 30 mins. Then, added a solution of 1-(chloroacetyl)-4-methylpiperazine (1.5 equiv) in dry DMF (10 mL) at 0° C., stirred for 1 h at 0° C. to RT. The progress of the reaction was monitored by TLC. After completion, reaction mixture was poured into ice water and extracted with EtOAC. The combined extracts were washed with water, brine, dried over anhydrous Na2SO4, filtered and evaporated. The crude residue was purifying by preparative HPLC to get tert-butyl (trans)-2-(1,1′-biphenyl-4-yl)cyclopropyl(2-(4-methylpiperazin-1-yl)-2-oxoethyl)carbamate derivative
