Reaction Steps

To a solution of 2-(4-chloro-7-methylquinazolin-2-yl)phenol (450 mg, 1.66 mmol) in 10 mL DMF was added a solution of (R)-tert-butyl 2-((benzyloxy)methyl)piperazine-1-carboxylate (610 mg, 1.99 mmol) in DMF and triethylamine (0.46 mL). The reaction mixture was then refluxed at 85° C. for 30 minutes, quenched with water, extracted twice with CH2Cl2, dried over Na2SO4, and concentrated to give (R)-tert-butyl 2-((benzyloxy)methyl)-4-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)piperazine-1-carboxylate (760 mg, 85%). This material was used in the next step without further purification. LC/MS: m/z 541.5 (M+H)+ at 3.37 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
