Procedure

To a stirring suspension of Example B3 (65 mg, 0.164 mmol), TBTU (79 mg, 0.246 mmol) and (R)-1-(4-fluorophenyl)-2-methoxyethanamine (40.5 mg, 0.197 mmol; prepared according to the published method: J. Med. Chem. (1999), 42(24), 4981) in DMF (2 ml) was added DIEA (0.171 ml, 0.984 mmol). The resulting clear solution was stirred at RT overnight. After stirring overnight, the reaction was diluted with satd. NaHCO3 and extracted with EtOAc (2×). The combined organics were washed with satd. NaHCO3 (1×), satd. LiCl (2×), and brine (1×), dried (MgSO4), evaporated in vacuo and purified by reverse phase chromatography. Pure fractions were pooled, treated with satd. NaHCO3 (pH 8) and extracted with EtOAc (3×). The combined organics were washed with satd. NaHCO3 (1×), brine (1×), dried (MgSO4), and evaporated to afford N-(3-fluoro-4-(2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yloxy)phenyl)-N′-((R)-1-(4-fluorophenyl)-2-methoxyethyl)cyclopropane-1,1-dicarboxamide as an oil. This was dissolved in 4:1 MeCN/H2O, treated with certified 0.1N HCl (1.37 ml, 1.0 eq), frozen and lyophilized to afford 63 mg (66% yield) of the HCl salt as a solid. 1H NMR (400 MHz, DMSO-d6): δ 10.64 (s, 1H), 8.49-8.48 (m, 2H), 8.44-8.42 (m, 1H), 8.18 (brs, 1H), 7.89-7.85 (m, 1H), 7.54 (brs, 1H), 7.48-7.35 (m, 4H), 7.16-7.11 (m, 2H), 6.92 (brs, 1H), 5.13-5.06 (m, 1H), 3.89 (s, 3H), 3.61-3.56 (m, 1H), 3.49-3.46 (m, 1H), 3.25 (s, 3H), 1.45-1.33 (m, 4H); MS (ESI) m/z: 516.1 (M+H+).
