Reaction Steps

(2S,4R)-N-(4-Chloro-phenyl)-N-[1-(4-hydroxy-benzoyl)-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl]-acetamide (300 mg, 0.693 mmol) was dissolved in DMF (10 mL) at room temperature. Cs2CO3 (1.12 g, 3.46 mmol) was added followed by 3-chloro-propane-1-sulfonic acid dibenzylamide (350 mg, 1.03 mmol) and the reaction was allowed to stir overnight. The mixture was partitioned between methylene chloride and water; the organic layer was dried over Na2SO4, filtered and concentrated. The crude residue was purified by silica gel chromatography (2/1 hexanes/ethyl acetate) to afford the product.
