Procedure

To a stirred solution of (2-3a) (60 mg) in tetrahydrofuran (3 mL) was added lithium hydroxide monohydrate (20 mg) in water (3 mL) and the mixture was stirred for 16 h. The reaction mixture was then concentrated at reduced pressure and resulting oil was purified by flash column chromatography (silica gel, 30:3:3 to 50:5:5% ethanol/ammonium hydroxide/water in ethyl acetate) to give 2-4a.
