Procedure

To a solution of 1-(4-(5-bromopyrimidin-2-ylamino)benzyl)piperidine-4-carboxylic acid 17 (0.05 mmol) in 1,4-dioxane (1.0 mL) is added 4-(trifluoromethoxy)phenylboronic acid (0.05 mmol), 3M Na2CO3 (0.15 mmol) and Pd(PPh3)4 (0.0025 mmol). The reaction is evacuated and backfilled with nitrogen twice then heated at 150° C. for 10 min. Purification by preparative HPLC (ACN gradient 10-70%) affords 1-(4-(5-(4-(trifluoromethoxy)phenyl)pyrimidin-2-ylamino)benzyl)piperidine-4-carboxylic acid A5. 1H NMR (400 MHz, d6-DMSO) δ 10.06 (s, 1H), 8.89 (s, 2H), 7.88 (M, 4H), 7.48 (d, J=8.4 Hz, 2H), 7.42 (d, J=8.0 Hz, 2H), 4.23 (s, 2H), 2.95 (m, 1H), 2.51 (m, 4H), 2.09 (m, 2H), 1.71 (m, 2H). MS (m/z) (M+1)+: 473.2.
