Reaction Steps

4-(3-Methyl-4-phenoxy-phenylamino)-quinazoline-6-carbaldehyde is prepared by adding NaIO4 (1.5 mL, 0.65 M in H2O) to a slurry of silica gel (1 g) in DCM (6 mL) followed by the addition of {2,3-dihydroxy-3-[4-(3-methyl-4-phenoxy-phenylamino)-quinazolin-6-yl]-propyl}-carbamic acid tert-butyl ester (from Step A, ˜0.64 mmol) in DCM (2 mL). The reaction mixture stirs for 1 hour, is filtered and washed with DCM (20 mL), and concentrated to give 280 mg of crude product. The product is used without further purification in Step E.
