Reaction Steps

A mixture of 4-fluoronitrobenzene (2.8 g, 20 mmol) and 2-(methylamino)ethanol (8.9 g, 120 mmol) in N-methylpyrrolidinone (80 mL) is heated for 19 hours in a 85° C. oil bath. After cooling to room temperature, the reaction mixture is partitioned between ethyl acetate and water. The organic phase is washed five times with water and with saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure to give 2-(methyl-4-nitroanilino)ethanol (3.1 g, 79%) as a yellow solid.
