Vorschrift

(S)-2-hydroxy-1-(4-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)piperazin-1-yl)-4-methylpentan-1-one (90 mg, 0.20 mmol) was dissolved in 1 mL CH2Cl2 and treated with 1 equivalent of 2.0 M HCl in ether (100 μL, 0.20 mmol). The formed precipitate was filtered and vacuum dried to obtain (S)-2-hydroxy-1-(4-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)piperazin-1-yl)-4-methylpentan-1-one hydrochloride.
