Reaction Steps

A solution of benzyl((R)-1-(tert-butoxycarbonyl)pyrrolidin-3-yl)methylcarbamate (0.20 g, 0.60 mmol) and 4 M HCl in dioxane (10 mL) was stirred for 3 h at room temperature. After evaporating the solvent under reduced pressure, the resulting solid was triturated with Et2O and dried under vacuum, then taken up in CH2Cl2 (10 mL). To this solution was added 2-(4-chloro-7-methylquinazolin-2-yl)phenol (0.16 g, 0.60 mmol) and 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 CH2Cl2 solution was 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%). LC/MS: m/z 469.1 (M+H)+ at 2.58 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
