Reaction Steps

A mixture of 2-methoxy-5-nitrophenol (4.86 g), cyclopentyl bromide (3.4 ml) and potassium carbonate (4.8 g) in N,N-dimethylformamide (50 ml) was stirred at 50° C. for 3 hours. Then the mixture was poured into a mixture of ethyl acetate and aqueous sodium bicarbonate. The organic phase was separated, washed with aqueous sodium bicarbonate and brine, dried over magnesium sulfate and concentrated. The resultant solid was collected and washed with isopropyl ether to give 3-cyclopentyloxy-4-methoxy-1-nitrobenzene (5.05 g).
