Procedure

200 mg of 2-(5-cyclopropyl-4-methyl-1H-pyrazol-3-yl)-5-methoxy-N-(pyridin-4-yl)pyrimidin-4-amine 1-16-1 (0.62 mmol, 1.0 eq.), 184.86 mg of methyl 3-(bromomethyl)-2,4-dichlorobenzoate (0.62 mmol, 1.0 eq.) and 31.0 mg of 60% sodium hydride in paraffin oil were suspended in 6.3 mL of dry THF and stirred for 20 hours at rt. The reaction mixture was partitioned between water and DCM/propan-2-ol 4:1. The separated aqueous layer was extracted three times with DCM/propan-2-ol 4:1. The combined organic layers were dried over sodium sulfate and concentrated in vacuo. The purification by flash chromatography and preparative HPLC of the residue provided 37.5 mg (0.07 mmol, 11%) of analytically pure target compound.
