Participants

Reaction Steps

To a solution of (R)-tert-butyl 2-((benzyloxy)methyl)-4-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)piperazine-1-carboxylate (760 mg, 1.72 mmol) in 15 mL CH2Cl2 was added 10 mL of TFA. The reaction was stirred for 1 hour. TFA was removed under vacuum and the reaction was neutralized using a 1 M NaOH solution. The aqueous layer was extracted twice with CH2Cl2, dried over Na2SO4, filtered, and concentrated to obtain 2-(4-((R)-3-((benzyloxy)methyl)piperazin-1-yl)-7-methylquinazolin-2-yl)phenol (570 mg, 92%). This material was used in the next step without further purification. LC/MS: m/z 441.5 (M+H)+ at 2.44 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
