Reaction Steps

A mixture of benzyl ((R)-1-(tert-butoxycarbonyl)pyrrolidin-3-yl)methylcarbamate (0.20 g, 0.60 mmol) and 4 M HCl (10 mL) in dioxane was stirred at room temperature for 3 h. After evaporating the solvent under reduced pressure, the solid was triturated with Et2O, dried under vacuum, and taken up in CH2Cl2 (10 mL). 2-(4-Chloro-7-methylquinazolin-2-yl)phenol (0.16 g, 0.60 mmol) was added to this solution, followed by the addition of triethylamine (0.25 mL, 1.8 mmol). The reaction mixture was stirred at room temperature overnight, then diluted with CH2Cl2 and washed with water. The combined organic layers were dried over Na2SO4, filtered, and concentrated. Purification via silica gel chromatography using 0-40% EtOAc in hexanes gave benzyl ((R)-1-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)pyrrolidin-3-yl)methylcarbamate as a colorless oil (0.19 g, 68% yield). LC/MS: m/z 469.1 (M+H)+ at 2.58 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
