YieldReaction ConditionsOperation in experiment
With sulfuric acid; at 0 - 70℃; for 15.08h; Step C:; A solution of compound V-3 (5.89 g, 28.44 mmol) in MeOH (60 mL) was cooled in an ice bath, then H2SO4 (Cone, 5 mL) was added dropwise over 5 minutes. The resulting reaction mixture was heated at 700C for 15 hours, then the solvent was removed and the resulting residue was partitioned between water (100 mL) and ethyl acetate (200 mL). The organic layer was separated and aqueous layer was extracted with ethyl acetate (3x100 mL). The combined organic phases were washed with water, brine, dried over MgSO4, filtered and concentrated to give compound V-4 (m/z (ES) (M+H)+= 222), which was used in the next step without further purification.
