反応手順

80 mg of 2-(1H-indazol-3-yl)-5-methoxy-N-(pyridin-4-yl)pyrimidin-4-amine (1-6-1, 0.251 mmol, 1. eq.) were suspended in dry tetrahydrofuran under a nitrogen atmosphere. 30.2 mg of sodium hydride (60% purity) were added and stirred at room temperature for 10 minutes. Then 59.7 mg of 2-(bromomethyl)-1-chloro-3-fluoro-4-methylbenzene were added. The reaction mixture was stirred for 18 hours at room temperature. Then the mixture was partitioned between half saturated aq. ammonium chloride solution and dichloromethane/isopropanol 4:1. The phases were separated and the aqueous layer was extracted twice with dichloromethane/isopropanol 4:1. The combined organic layers were washed with brine, dried over a silicone filter and concentrated in vacuo. Preparative HPLC purification provided 29 mg (0.06 mmol, 24.1%) of the analytically pure target compound.
