Reaction Steps
To a solution of cis-4-amino-8-bromo-2-cyclopropyl-6-trifluoromethyl-1,2,3,4-tetrahydro-quinoline (Example 100A) (250 mg, 0.75 mmol) in anhydrous dichloromethane (10 mL) was added acetic acid (112 mg, 1.90 mmol), followed by 3,5-bis(trifluoromethyl)benzaldehyde (180 mg, 0.75 mmol) and sodium triacetoxyborohydride (791 mg, 3.73 mmol). The reaction was stirred at room temperature for 5 h. The reaction mixture was then diluted with dichloromethane and washed with 1N NaOH. The organic layer was separated, dried over magnesium sulfate, filtered and concentrated in vacuo to afford the title crude product (420 mg) which was used without further purification. 1H NMR (CDCl3) δ 0.3 (m, 2H), 0.6 (m, 2H), 1.0 (m, 1H), 7.5 (s, 1H), 7.8 (s, 2H), 7.9 (s, 2H).
