To a solution of (R)-3-(4′-(2-(2-methylpyrrolidin-1-yl)ethyl)biphenyl-4-yl)propanoic acid (40 mg, 0.119 mmol), tert-butyl 2-amino-2-methylpropanoate hydrochloride (27.8 mg, 0.142 mmol), and TEA (0.050 mL, 0.356 mmol) in tetrahydrofuran (1 mL) and acetonitrile (1 mL) was added HATU (54.1 mg, 0.142 mmol). The reaction mixture was stirred at 60° C. for 1.5 h and 1M HCl was added to neutralize the reaction solution. The resulting mixture was purified by HPLC to give the title compound. LCMS m/z=479.4 [M+H]+; 1H NMR (400 MHz, CD3CN) δ ppm 1.27 (d, J=6.9 Hz, 0.4H), 1.37 (s, 6H), 1.41 (s, 9H), 1.46 (d, J=6.5 Hz, 2.6H), 1.70-1.82 (m, 1H), 2.01-2.12 (m, 2H), 2.23-2.33 (m, 1H), 2.45 (t, J=7.8 Hz, 2H), 2.93 (t, J=7.6 Hz, 2H), 3.05-3.22 (m, 4H), 3.39-3.48 (m, 1H), 3.53-3.62 (m, 1H), 3.72-3.82 (m, 1H), 6.60 (s, 1H), 7.34 (d, J=8.2 Hz, 2H), 7.39 (d, J=8.2 Hz, 2H), 7.58 (d, J=8.2 Hz, 2H), 7.63 (d, J=8.2 Hz, 2H).
