실험 절차

To a solution of 4-[7-(2-methanesulfonyloxy-ethoxy)-quinazolin-4-yl]-piperidine-1-carboxylic acid tert-butyl ester (40.6 mg, 0.09 mmol) in DMSO (0.4 mL) was added (S)-(+)-2-pyrrolidinemethanol (90.9 mg, 0.9 mmol). The mixture was stirred at 120° C. overnight and subsequently partitioned between EtOAc and water. The combined organic extracts were washed with brine, dried over Na2SO4 and evaporated. The residue was treated with 50% TFA/CH2Cl2 (8 mL) for 2 h, the solvents (TFA/CH2Cl2) were removed under reduced pressure to provide the desired product. LC-MS (ESI) calcd for C20H29N4O2 (MH+) 357.2, found 357.2.
