Versuchsvorschrift

5-pyrimidin-5-yl-6-(2-quinolin-6-ylethynyl)pyridin-2-amine G2b (600 mg, 1.86 mmol) is mixed with NMP (10 ml) and DIPEA (1.42 ml, 8.35 mmol). 2-Bromobutanoyl bromide (985 μl, 8.17 mmol) is added dropwise. The mixture stirred for 1 h at RT. The mixture is diluted with DCM and extracted with a saturated aqueous solution of NaHCO3. The combined organic layers are dried over MgSO4 and concentrated in vacuo. The crude intermediate is mixed with a THF solution of methylamine (2 mol/l, 5 ml, 10 mmol) and stirred at RT for 16 h. The mixture is diluted with DCM and extracted with a saturated aqueous solution of NaHCO3. The combined organic layers are dried over MgSO4 and concentrated in vacuo. The product is purified by RP HPLC. Yield: 250 mg (32%). HPLC-MS: M+H=423; tR=1.25 min (*Method—1).
