Procedure

cis-4-[(3,5-bis-trifluoromethyl-benzyl)-amino]-8-bromo-2-cyclopropyl-6-trifluoromethyl-3,4-dihydro-2H-quinoline (Example 100B) (420 mg, 0.75 mmol) and pyridine (148 mg, 1.88 mmol) were dissolved in anhydrous dichloromethane (15 mL) and cooled to 0° C. Methyl chloroformate (142 mg, 1.5 mmol) was added over 1 min. The reaction was stirred at 0° C. for 1 h, then at room temperature for 24 h. The reaction mixture was then diluted with 50 mL of dichloromethane, and washed twice with 1N HCl. The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo to afford the title product (400 mg) which was used without further purification. MS m/z 618.8 (M+).
