실험 절차

A slurry of methyl 4-((methyl(piperidin-2-ylmethyl)amino)methyl)benzoate hydrochloride salt (200 mg, 0.58 mmol) in dichloroethane (6 mL) was stirred as diisopropylethylamine (225 mg, 1.74 mmol) was added. After 30 minutes, 4-(4-bromophenoxy)benzaldehyde (160 mg, 0.58 mmol) was added to the reaction mixture. After 20 minutes, solid triacetoxyborohydride (147 mg, 0.7 mmol) was added and the reaction was stirred for 17 hours. Solvent was removed under reduced pressure. The residue was dissolved in a mixture of THF and methanol and treated with lithium hydroxide to give a basic solution. The reaction was stirred for 17 hours, concentrated to dryness, and purified by reverse phase preparative HPLC using a gradient of acetonitrile in water containing 0.1% TFA. Relevant fractions were combined to give 40 mg of 4-[[[[(RS)-1-[[4-(4-bromophenoxy)phenyl]methyl]-2-piperidinyl]methyl]methylamino]methyl]benzoic acid; 1NMR (400 MHz, DMSO-d6) δ 7.93 (d, 2H), 7.57 (d, 2H), 7.52 (m, 4H), 7.06 (d, 2H), 6.96 (d, 2H), 4.61 (dbr, 2H), 4.18 (dbr, 2H), 3.24 (m, 1H), 2.34 (s, 3H), 2.00 (m, 1H), 1.63 (m, 5H) ppm.
