Participants

Reaction Steps

To 3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (34.9 mg, 0.124 mmol) in CH2Cl2 (3 mL) was added 4-(dimethylamino)phenyl isocyanate (21 mg, 0.129 mmol) and stirred for two days. The resulting material was purified by HPLC. The product was dried in vacuo to afford Compound 116 as a waxy solid (13.5 mg, 25%).
