A stirred solution of 3-nitrophenol (1.39 g, 10 mmol), 1-naphthaleneethanol (1.89 g, 11 mmol), and triphenylphosphine (2.9 g, 11 mmol) in 100 ml of tetrahydrofuran was treated with a solution of 2.22 g (11 mmol) of diisopropylazodicarboxylate added dropwise. The resulting mixture was stirred overnight, and then concentrated and redissolved in a minimum amount of ethyl acetate. Purification on a silica gel column, eluting with 10% ethyl acetate in hexane, delivered 2.0 g of the ether.
