Procedure

The reaction mixture of 3-(3-endo-amino-8-azabicyclo[3.2.1]octane-8-carbonyl)benzonitrile hydrochloride (300 mg, 1.03 mmol), commercially available 2-(2,4-dichlorophenoxy)-2-methylpropanoic acid (310 mg, 1.24 mmol), EDCI (300 mg, 1.54 mmol), HOBT (210 mg, 1.54 mmol) and triethylamine (0.75 mL, 5.38 mmol) in CH2Cl2 (10 mL) was stirred 18 h. The resulting mixture was washed with satd. aq. NaHCO3 (5 mL) and brine (5 mL) successively, then dried over MgSO4, filtered and evaporated to give a residue which was purified by column chromatography (ethyl acetate: CH2Cl2=1:1) to give N-(8-(3-cyanobenzoyl)-8-azabicyclo[3.2.1]octan-3-endo-yl)-2-(2,4-dichlorophenoxy)-2-methylpropanamide (378 mg, 0.78 mmol, 76% yield) as a white foam. 1H NMR (CDCl3, 400 MHz): δ 1.55 (s, 6H), 1.85 (m, 2H), 2.00 (m, 3H), 2.20 (m, 3H), 2.50 (m, 1H), 4.04 (br s, 1H), 4.28 (q, 1H), 4.86 (br s, 1H), 7.05 (d, 1H), 7.22 (dd, 1H), 7.44 (d, 2H), 7.58 (m, 2H), 7.77 (m, 3H).
