Procedure

A mixture of EXAMPLE 187A (0.158 g), (3S,4R)-4-amino-1-benzylpiperidin-3-ol, hydrochloric acid (0.049 g), and triethylamine (0.1 mL) in dioxane (2 mL) was heated at 100° C. overnight. The solvent was removed, and the residue was re-dissolved in 1:1 methanol:dimethylsulfoxide (3 mL). It was then purified by reverse phase Prep HPLC. The residue was purified by reverse phase HPLC on a C18 column using a gradient of 20-80% acetonitrile/0.1% TFA in water. The desired fractions were collected, and the organic solvent was partially removed under reduced pressure. The resulting mixture was treated with saturated aqueous NaHCO3 mixture. It was then extracted with ethyl acetate three times. The combined organic layers were washed with brine, dried (MgSO4), filtered, and concentrated to give the desired product. 1H NMR (500 MHz, dimethylsulfoxide-d6) δ 11.14 (s, 1H), 8.69 (d, 1H), 8.14 (d, 1H), 7.77 (dd, 1H), 7.51 (d, 1H), 7.29-7.41 (m, 9H), 7.10-7.13 (m, 1H), 7.13 (d, 2H), 6.84 (dd, 1H), 6.63 (dd, 1H), 6.38 (s, 1H), 6.13 (d, 1H), 5.21-5.22 (br s, 1H), 3.82 (m, 2H), 3.62 (br s, 2H), 3.01 (br s, 4H), 2.71-2.82 (m, 4H), 2.12-2.15 (m, 7H), 1.94 (br s, 2H), 1.81 (br s, 2H), 1.36-1.39 (m, 2H), 0.92 (s, 6H).
