Reaction Steps

To a solution of N-(7-(5-amino-2-methylphenyl)isoquinolin-3-yl)cyclopropanecarboxamide (53.8 mg, 0.144 mmol) in methylene chloride (2.0 mL, 31 mmol) was added pyridine (0.10 mL, 1.2 mmol) and 1-methyl-1H-pyrazole-4-carbonyl chloride (27.7 mg, 0.192 mmol). The reaction mixture was stirred at room temperature for 15 hours. The reaction mixture was then poured into 50 mL dichloromethane, washed with aqueous NaHCO3, dried over MgSO4, filtered, and evaporated in vacuo. The crude product was purified via reverse phase HPLC and lyophilized to yield 37.1 mg (61%) of N-(3-(3-(cyclopropanecarboxamido)isoquinolin-7-yl)-4-methylphenyl)-1-methyl-1H-pyrazole-4-carboxamide.
