実験手順

6-(8-Oxa-3-azabicyclo[3.2.1]octan-3-yl)-2-chloro-N4-isopropylpyrimidine-4,5-diamine 3-(dimethylamino)propanoate (48, 0.500 g, 1.68 mmoles) was dissolved in dimethylformamide and 3-dimethylaminopropionic acid (0.310 g, 2.02 mmoles) and isobutyl 2-isobutoxyquinoline-1(2H)-carboxylate (IIDQ, 0.699 mL, 2.35 mmoles) were added. The reaction mixture was allowed to stir at room temperature for 18 hours, concentrated, and purified by silica gel column chromatography (5-10% ethanol in dichloromethane) to provide N-(4-(8-oxa-3-azabicyclo[3.2.1]octan-3-yl)-2-chloro-6-(isopropylamino)pyrimidin-5-yl)-3-(dimethylamino)propanamide (49) as a tan solid. Yield: 0.350 g (53%). LCMS (Waters walk-on); 2.43 min., 397.2, M+H.
