Participants

Reaction Steps

A solution of 5.00 g 7-(2-quinolinylmethoxy)-2-naphthaleneamine (17 mmol), prepared according to the procedure of Example 7, 1.7 g triethylamine (17 mmol) and 2.18 g ethanesulfonyl chloride (17 mmol) in 50 mL tetrahydrofuran is refluxed overnight. The solvent is removed and the residue is partitioned between methylene chloride and saturated sodium bicarbonate. After drying over potassium carbonate, the organic layer is freed of solvent to afford 5.00 g of a brown gum. Chromatography on alumina and elution with 9:1 methylene chloride/ethyl acetate affords 1.4 g of a white solid which is recrystallized from ethyl acetate. Rechromatography on HPLC and final recrystallization from ethyl acetate affords 0.6 g (9%) of white crystals, m.p. 166°-167.5° C.
