Procedure

To a suspension of sodium hydride (4.2 mg, 60% dispersion in mineral oil, 0.10 mmol) in N,N-dimethylformamide (2.5 mL) was added cis-4-[(3,5-bis-trifluoromethyl-benzyl)-methoxycarbonyl-amino]-7-hydroxymethyl-6-methoxy-2-methyl-3,4-dihydro-2H-quinoline-1-carboxylic add ethyl ester (Example 85) (50 mg, 0.087 mmol). After the reaction was stirred at room temperature for 30 min, iodomethane (60 μL, 0.96 mmol) was added, and the reaction was stirred for 18 h. The reaction mixture was then poured into water and extracted with ethyl acetate (2×20 mL). The combined organic extracts were dried over magnesium sulfate, filtered and concentrated in vacuo. The excess N,N-dimethylformamide was azeotroped off with heptanes. Purification by silica gel chromatography using 15-25% ethyl acetate/hexanes as eluent afforded the title product (30 mg, 59%): 1H NMR (CDCl3) δ 1.1 (d, 3H), 1.3 (t, 3H), 3.4 (s, 3H), 3.75 (s, 3H), 3.8 (s, 3H), 6.4 (s, 1H), 7.4 (s, 1H), 7.75 (s, 2H), 7.8 (s, 1H).
