Reaction Steps

Add 215 mg (4.3 mmol) of hydrazine hydrate at RT to 100 mg (0.215 mmol) of 3-{[5-(4-methoxy-phenyl)-6-phenylfuro[2,3-d]pyrimidin-4-yl]amino}phenylacetic acid methyl ester (Example 28), dissolved in 1.5 ml of THF and 2 ml of methanol. Stir the mixture at 65° C. for 1 h and at RT overnight and then concentrate under reduced pressure. After stirring with diisopropyl ether, filter off the solid with suction and dry under reduced pressure. 89.3 mg (89.3% of theory) of the target product are obtained.
