Procedure

tert-Butyl (S)-pyrrolidin-3-ylcarbamate (245 mg, 1.31 mmol) was dissolved in 1.8 mL of anhydrous CH2Cl2 and cooled to 0° C. 2-(4-Chloro-7-methylquinazolin-2-yl)phenol (300 mg, 1.1 mmol) dissolved in 1.8 mL of anhydrous CH2Cl2 was added dropwise to the mixture followed by triethylamine (134 mg, 184 μL, 1.32 mmol). The reaction was allowed to warm to room temperature and was stirred overnight. Purification via silica gel chromatography using 10-100% ethyl acetate/hexanes gave tert-butyl (S)-1-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)pyrrolidin-3-ylcarbamate. LC/MS: m/z 421.0 (M+H)+ at 2.84 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
