Reaction Steps
Ethyl 2-(3-(cyclopropylmethoxy)-4-nitrophenyl)acetate (0.5 g) was dissolved in 10 mL anhydrous DMF and NaH (60% wt. in oil, 0.13 g, mmol) was added at 0° C. The reaction mixture was stirred for 0.5 h at 25° C. and 1,4-dibromobutane (0.24 g, mmol) was added drop wise at 0° C. The reaction mixture was stirred at 0° C. for 1 h and saturated NH4Cl solution (10 mL) was added. The reaction mixture was extracted with EtOAc (3×20 mL) and the combined organic phases were washed with water (3×20 mL) and brine (20 mL), and dried over MgSO4, filtered and concentrated under reduced pressure to give ethyl 1-(3-(cyclopropylmethoxy)-4-nitrophenyl)cyclopentanecarboxylate (380 mg) as a colorless oil.
