Reaction Steps

This compound can be prepared as in Example 32 by reacting 2-methoxy-4-[4-(4-methyl-4-oxido-1,4-azaphosphinan-1-yl)piperidin-1-yl]aniline with 2,4,5-trichloropyrimidine to generate 2,5-dichloro-N-{2-methoxy-4-[4-(4-methyl-4-oxido-1,4-azaphosphinan-1-yl)piperidin-1-yl]phenyl}pyrimidin-4-amine. 2,5-dichloro-N-{2-methoxy-4-[4-(4-methyl-4-oxido-1,4-azaphosphinan-1-yl)piperidin-1-yl]phenyl}pyrimidin-4-amine is then reacted with 5-cyclopropyl-1,3-oxazol-2-amine according to the procedure described in Example 32.
