Reaction Steps

In a mixture of 20 ml THF, 5 ml H2O, and 1 ml 50 wt % NaOH (aq) was dissolved methyl 1-(4-{[(3,4-dichloro-5-methyl-1H-pyrrol-2-yl)carbonyl]amino}piperidin-1-yl)isoquinoline-3-carboxylate (Example 301; 70 mg). The solution was stirred at 80° C. for 1 hr. The solution was cooled to room temperature, diluted with EtOAc and acidified with dilute HCl (aq). The EtOAc fraction was isolated, at which time a white solid precipitated from solution. The solid was collected by filtration and washed with acetonitrile to yield 50 mg white solid product.
