Reaction Steps

To a solution of cis-4-[(3,5-bis-trifluoromethyl-benzyl)-methoxycarbonyl-amino]-6,7-bis-bromomethyl-2-methyl-3,4-dihydro-2H-quinoline-1-carboxylic acid ethyl ester (Example 27B) (50 mg, 0.71 mmol) in 0.25 ml benzene was added benzyl tri-n-butylammonium chloride (23 mg, 0.71 mmol) and 30% NaOH (28 μl). The reaction mixture was heated to 80° C. for 4 hours. The mixture was diluted with 0.75 ml ethyl acetate. The organic layer was separated and the aqueous phase was extracted with ethyl acetate (2×0.25 ml). The combined extracts were dried (MgSO4), filtered and concentrated. The crude material was chromatographed on silica gel (25% ethyl acetate:hexane) to afford the title product (10 mg, 25%). MS m/z 561 (M+); 1H NMR (CDCl3) δ3.85 (s, 3H), 6.85 (s, 1H).
