Reaction Steps

To 9.3 mg (0.16 mmol) isopropylamine in 0.5 mL DMSO are added 31 mg (0.10 mmol) 2-[4-(2-chloro-pyrimidin-5-ylethynyl)-phenyl]-N-ethyl-propionamide (XVIII.1) in 1 mL DMSO, followed by 254 (16 mmol) DIPEA. The mixture is stirred at rt for 12 h. After that time, the mixture is directly purified by HPLC (preparative column: Sunfire; eluent A: water+0.1% TFA, eluent B: MeOH) to yield the desired product.
