실험 절차

A solution of compound (11b) (60 g) prepared in EXAMPLE 20 and aqueous HF (2 N, 135 mL) in IPA (240 mL) was stirred. Saturated aqueous NaHCO3 (120 mL) was added and the mixture was extracted with EtOAc (600 mL). The separated aqueous layer was extracted with EtOAc (300 mL) and the combined organic layer was washed with saturated aqueous NaCl (300 mL), dried with Na2SO4, filtered, and the filter cake was washed with EtOAc (200 mL). The filtrate was concentrated to furnish 43.5 g of crude compound (11c) (84.3% HPLC purity, 84% yield) which was directly used without purification in EXAMPLE 22.
