Procedure

120 ml of methanol and 2 ml of concentrated hydrochloric acid were given to 8.05 g of 4-[(R)-(1-Phenylethyl) amino]-7-[2-(tetrahydropyran-2-yloxy)ethoxy]-6-nitroquinazoline. After stirring for 1.5 hours at 50° C. the reaction mixture was neutralized with concentrated aqueous sodium carbonate solution and evaporated. The solid residue was dissolved in ethyl acetate and the obtained solution was washed with water, with concentrated aqueous sodium chloride solution, dried over magnesium sulfate solution and evaporated. The obtained yellow residue was stirred with 20 ml of tert-butyl methyl ether, suction filtered and dried in an exsiccator. Yield: 4.53 g (91% of theory); melting point: 192° C.–194° C.; mass spectrum (ESI−): m/z=353 [M−H]−.
