Reaction Steps

9.1 mg (0.22 mmol) of lithium hydroxide monohydrate were added to a solution of 60 mg (0.11 mmol) of methyl 2-methyl-4-[(3-methyl-2-{-4-[(5-oxo-2-phenyl-5,6-dihydro-4H-1,3,4-oxadiazin-4-yl)methyl]phenyl}butanoyl)amino]-2,3-dihydro-1H-indene-2-carboxylate (Example 136A) in 2 ml of THF and 2 ml of water, and the mixture was stirred at 60° C. for 8 h. The reaction mixture was then adjusted to pH 4 with 1 M hydrochloric acid and concentrated to dryness under reduced pressure. The crude product obtained was purified by flash chromatography on silica gel (mobile phase cyclohexane/ethyl acetate 10:1→4:1→1:1 or dichloromethane/methanol 10:1). This gave 43 mg (0.08 mmol, 74% of theory) of the title compound.
