Procedure
To a solution of the yellow oil obtained in Example 45 and mercaptoacetic acid (100 mg, 1.1 mmol) in N,N-dimethylformamide (5 mL) was added lithium hydroxide monohydrate (80 mg, 1.9 mmol), and the mixture was stirred at room temperature for 14 hr. The reaction mixture was poured into 10% aqueous sodium hydrogencarbonate solution, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was dried using a Presep Dehydration tube (manufactured by Wako Pure Chemical Industries, Ltd.), and concentrated. The residue was purified by silica gel column chromatography (10%-80% ethyl acetate/hexane) to give the title compound (155 mg, yield 66%, 2 steps) as a yellow oil.
