Reaction Steps

A mixture of 4-chloro-7-(3,5-dimethyl-4-isoxazolyl)-6-(methoxy)-3-nitroquinoline (for a preparation see Intermediate 18, 0.4 g, 1.2 mmol) and (1R)-1-(2-pyridinyl)ethanamine (2 eq, 0.293 g) in CH3CN (20 ml) was heated at 60° C. for 2 h. The mixture was extracted with DCM. The organic phase washed with saturated aqueous Sodium hydrogen carbonate and dried over Na2SO4. The solvent was evaporated under reduced pressure and the residue taken up in diethyl ether. The precipitate was filtered off and dried in vacuo to give 7-(3,5-dimethyl-4-isoxazolyl)-6-(methoxy)-3-nitro-N-[(1R)-1-(2-pyridinyl)ethyl]-4-quinolinamine (0.4 g) which was used without purification in the next step.
