Reaction Steps

To a pre-dried flask under nitrogen atmosphere was added cis-8-amino-4-[(3,5-bis-trifluoromethyl-benzyl)-methoxycarbonyl-amino]-6-chloro-2-methyl-3,4-dihydro-2H-quinoline-1-carboxylic acid ethyl ester (Example 109) (30 mg, 0.053 mmol), followed by anhydrous dichloromethane (2 mL), pyridine (0.5 mL), and acetyl chloride (0.015 mL, 0.21 mmol). The reaction was stirred overnight at room temperature before ethyl acetate was added, and the mixture was extracted three times with 1N HCl, followed by brine. The organic layer was dried over sodium sulfate, filtered and concentrated in vacuo to give the title product (33 mg, 100%) MS m/z 610 (M++H); 1H NMR (CDCl3) δ 7.8 (bs, 2H), 7.7 (bs, 1H), 7.65 (bs, 1H), 6.8 (bs, 1H), 3.8 (s, 3H), 2.1 (s, 3H).
