実験手順

2-(5-(5-bromopyrimidin-2-ylamino)-2-fluorophenoxy)ethyl methanesulfonate 46b (0.24 mmol) and methyl piperidine-4-carboxylate (0.48 mmol) are dissolved in NMP (2 mL) and heated to 90° C. for 3 h. The reaction mixture is cooled to rt and diluted with water and extracted with EtOAc (2×30 mL). The organic layer is washed with water, brine, dried over sodium sulfate, and concentrated to dryness. The crude product is purified by short SiO2 chromatography using DCM:hexane=9:1 as eluant to yield methyl 1-(2-(5-(5-bromopyrimidin-2-ylamino)-2-fluorophenoxy)ethyl)piperidine-4-carboxylate 47 as light brown solid. MS (m/z) (M+1)+: 454.1.
