Reaction Steps

4-Cyano-N-[5-[2-(3-methoxyphenyl)ethyl]-2H-pyrazol-3-yl]benzamide (Example 23) (0.2 g, 0.58 mmol) and NaOH (69 mg, 1.73 mmol) were added to a solution of ethanol/water (20 ml, 3:1) and heated at 80° C. until complete consumption of starting material was observed. Care was required as the amide further hydrolysed to the carboxylic acid. The reaction was extracted with DCM (3×50 ml), dried and the solvent was removed in vacuo to yield a white solid. This was triturated with DCM to afford a white solid (20 mg, 10%); 1H NMR (400.132 MHz, DMSO) δ 2.90 (s, 4H), 3.75 (s, 3H), 6.42 (s, 1H), 6.82-6.75 (m, 3H), 7.20 (t, 1H), 7.46 (s, 1H), 7.95 (d, 2H), 8.16-8.03 (m, 3H), 10.82 (s, 1H), 12.18 (s, 1H); MH+366.
