Diisopropylethylamine → 5-chloro-thiophene-2-carboxylic acid [3-(4-chloro-2-methyl-2H-pyrazol-3-yl)-4-(2-morpholin-4-yl-ethoxy)-phenyl]-amide

Participants

Reaction Steps

To a mixture of 3-(4-chloro-2-methyl-2H-pyrazol-3-yl)-4-(2-morpholin-4-yl-ethoxy)-phenylamine (0.100 g, 0.3 mmol), 5-chlorothiophene-2-carboxylic acid (0.049 g, 0.3 mmol), and HATU (0.114 g, 0.3 mmol) in DMF (4 mL), DIEA (0.157 mL, 0.9 mmol) was added, then the reaction mixture stirred at room temperature overnight. The crude product was purified by prep HPLC. The corresponding fractions were collected and lyophilized to give a TFA-salt of Compound 333 as a brown solid in 15.1% yield. LCMS m/z (%)=481.2 (M+H, 100). 1H NMR (400 MHz, DMSO-d6) δ: 10.41 (s, 1H), 9.95 (bs, 1H), 7.90-7.87 (m, 2H), 7.66 (s, 1H), 7.63 (d, J=2.6 Hz, 1H), 7.31-7.23 (m, 2H), 4.48-4.27 (m, 2H), 3.66 (s, 3H), 3.81-2.87 (m, 10H and water).
