Reaction Steps

To a solution of 2-(3-fluorophenyl)piperidine-3-carboxylic acid (3-tert-butylphenyl)amide (prepared above, 177.3 mg, 0.5 mmol) in 2 mL of dichloromethane was added Et3N (100 μL, excess), and 2-methylbenzoyl chloride (92.3 mg, 0.6 mmol) at room temperature. The resulting solution was then stirred at this temperature until completion of the reaction (10 min.). The reaction mixture was then directly loaded onto a silica gel column, and was purified by using ISCO (30% EtOAc in hexane) to give the final product 2-(3-fluorophenyl)-1-(2-methylbenzoyl)piperidine-3-carboxylic acid (3-tert-butylphenyl)amide (151.2 mg, 64% yield). 1H NMR (400 MHZ, CDCl3, mixture of rotomers): δ 7.91 (s, 0.6H), 7.85 (s, 0.4H), 7.18-7.46 (m, 9H), 7.11 (m, 1H), 6.95 (m, 1H), 6.67 (d, J=1.2 Hz, 1H), 3.36 (d, J=1.6 Hz, 0.4H), 3.26 (d, J=1.6 Hz, 1H), 3.05 (m, 1H), 2.89 (t, J=1.2 Hz, 1H), 2.45 (s, 1H), 2.02-2.40 (m, 4H), 1.70-1.84 (m, 3H), 1.44-1.64 (s, 1H), 1.32 (s, 6H), 1.25 (s, 1H). MS: (ES) m/z 473.2 (M+H+).
