Procedure

Compound 167 (0.06 g, 0.19 mmol) was dissolved in dichloroethane (2.0 mL) and the solution was added with N,N,N′-trimethylethylenediamine (62 μL, 0.57 mmol), acetic acid (63 μL, 0.57 mmol) and sodium triacetoxyborohydride (0.12 g, 0.57 mmol), followed by stirring at room temperature for 1 hour. The reaction mixture was added with water, extracted with ethyl acetate and the organic layer was concentrated. The residue was purified by silica gel column chromatography (ethyl acetate/methanol=9/1) to obtain Compound 188 (41 mg, 54%).
