(2-(4-Iodo-2-methoxypyridin-3-yl)-4-methyl-1H-imidazol-5-yl)(morpholino)methanone (0.007 g, 0.017 mmol) was dissolved in acetic acid (1 mL) and concentrated hydrochloric acid (1 mL) and this mixture was stirred at 100° C. for 1 hour. The mixture was then evaporated and the residue was dissolved in N,N-dimethylformamide (2 mL) and treated with triethylamine (100 μL, 0.72 mmol) and the hydrochloric acid salt of (S)-2-amino-1-[3-chlorophenyl]ethanol (0.010 g, 0.048 mmol). The mixture was heated at 90° C. for 4 hours, then the solvent was evaporated and the residue was purified by Prep HPLC (ammonium acetate/acetonitrile/water) to give the title compound (0.002 g, 25%) as a white solid. HPLC 100% (220 nm), LCMS (+ESI, M+H+) m/z 458; 1H NMR (400 MHz, methanol-d4) δ (ppm): 2.37 (3H, s), 3.45-4.0 (10H, m), 4.7-4.9 (1H, m, overlapped by D2O), 6.10 (1H, d, J=7.8 Hz), 7.10 (1H, d, J=7.6 Hz), 7.14-7.24 (3H, m), 7.36 (1H, s), 10.26 (1H, br s).
