実験手順

Dissolve phosphoric acid dibenzyl ester 4-(4-tert-butyl-phenylamino)-7-(3-trifluoromethyl-pyridin-2-yl)-quinazolin-2-ylmethyl ester (225 mg, 0.316 mmol) in methanol and add 10% palladium on carbon (218 mg). Stir the solution for 2 hours under 1 atmosphere of hydrogen gas. Filter the solution through celite and wash through with additional methanol. Concentrate under reduced pressure and triturate with ether to yield the desired product as a yellow solid.
