Participants

Reaction Steps

1 g of methyl 2,4-dichloro-3-({3-[5-methoxy-4-(pyridin-4-ylamino)pyrimidin-2-yl]-1H-indazol-1-yl}methyl)benzoate (2-16-1, 1.868 mmol, 1. eq.) were dissolved in 19 ml of dry THF and 2.2 ml of methanol. 4.67 ml of 2 M aqueous sodium hydroxide solution (9.34 mmol, 5 eq.) were added. The mixture was stirred for three hours at room temperature. The reaction mixture was partitioned between citric acid (pH 3) and ethyl acetate. This process dropped out a white precipitate which was filtered off and dried for three days to yield 992 mg (1.86 mmol, 99.8%) of the analytically pure target compound.
