Procedure
A 2 mL vial was charged with (R)—N-(4-(1-aminoethyl)-5-fluoro-2-methylphenyl)methanesulfonamide hydrochloride (14 mg, 0.049 mmol) and N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (17 mg, 0.044 mmol). A solution of 2-(trifluoromethyl)-5,6,7,8-tetrahydroquinoline-6-carboxylic acid (6.0 mg, 0.024 mmol) and N,N-diisopropylethylamine (21 uL, 0.12 mmol) in N-methylpyrrolidinone (0.4 mL, 4 mmol) was added, and the mixture stirred to dissolution. After 40 min the mixture was filtered and purified by reverse-phase HPLC (10-75% MeCN in 10 mM Et2NH/H2O) to afford the amide as a solid (8.4 mg, 72%). 1H NMR (400 MHz, CD3OD) δ 7.73 (app t, J=8.3 Hz, 1H), 7.53 (dd, J=3.8, 8.0 Hz, 1H), 7.23 (d, J=8.3 Hz, 1H), 7.14 (dd, J=1.4, 11.7 Hz, 1H), 5.19 (app pentet, J=7.0 Hz, 1H), 3.17-2.94 (m, 4H), 2.98 (s, 3H), 2.82-2.71 (m, 1H), 2.32 (s, 3H), 2.23-2.12 (m, 1H), 2.07-1.89 (m, 1H), 1.47 (d, J=7.0 Hz, 3H); m/z=474.4 (M+H)+.
