Reaction Steps

To a mixture of 3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-(2-piperidin-1-yl-ethoxy)-phenylamine (0.034 g, 0.09 mmol) and 2-chlorobenzoxazole (0.016 g, 0.11 mmol) in isopropanol (1 mL), DIEA (0.031 mL, 0.18 mmol)) was added. The reaction mixture was heated at 60° C. for 4 days, concentrated then subjected to a purification by prep HPLC. The corresponding fractions were collected and lyophilized to afford Compound 199 (TFA salt) as an off-white solid in 18.4% yield. LCMS m/z (%)=496 (M+H 79Br, 90), 498 (M+H 81Br, 100). 1H NMR (400 MHz, Acetone-d6) δ: 11.80 (bs, 1H), 8.04 (dd, J=2.8, 9.0 Hz, 1H), 7.91 (d, J=2.8 Hz, 1H), 7.61 (s, 1H), 7.48-7.42 (m, 2H), 7.36 (d, J=9.0 Hz, 1H), 7.27 (dt, J=1.0, 7.6 Hz, 1H), 7.18 (dt, J=1.2, 7.8 Hz, 1H), 4.72-4.63 (m, 1H), 4.60-4.5 (m, 1H), 3.80 (s, 3H), 3.81-3.42 (m, 4H and water), 2.95-2.82 (m, 2H), 1.95-1.80 (m, 4H), 1.55-1.30 9 (m, 2H).
