Reaction Steps

2-methoxy-5-nitro-phenol (508 mg, 3 mmoles) was dissolved in DMF (20 mL) under nitrogen atmosphere. K2CO3 (900 mg, 6.5 mmoles), KI (490 mg, 2.95 mmol) and ethyl bromide (0.250 mL, 3.3 mmoles) were added, and the suspension was heated to 40° C. for 28 hours. The mixture was diluted with AcOEt (60 mL) and extracted with 1N NaOH (40 mL) and water (40 mL). The organic layer was dried over Na2SO4 and evaporated to dryness. The crude was employed in the next step without purification.
