Reaction Steps

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 2-(4-(difluoromethoxy)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 7 (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-(difluoromethoxy)phenyl)pyrimidin-2-ylamino)benzyl)piperidine-4-carboxylic acid A4. 1H NMR (400 MHz, d4-MeOH) δ 8.64 (s, 2H), 7.78 (d, J=8.8 Hz, 2H), 7.56 (d, J=8.8 Hz, 2H), 7.32 (d, J=8.8 Hz, 2H), 7.16 (d, J=8.8 Hz, 2H), 6.78 (t, J=74.0 Hz, 1H), 4.11 (s, 2H), 3.31 (m, 2H), 2.92 (m, 2H), 2.36 (m, 1H), 2.02 (m, 2H), 1.81 (m, 2H). MS (m/z) (M+1)+: 455.2.
