実験手順

Sodium hydroxide (2N in water) (0.293 mL, 0.59 mmol) was added to a stirred suspension of methyl 2-((R)-2-methylmorpholino)-4-oxo-8-(1-phenylpyrrolidin-2-yl)-4H-chromene-6-carboxylate (105 mg, 0.23 mmol) in MeOH (2 mL)/water (2 mL) as described in example 3.00 to afford 2-((R)-2-methylmorpholino)-4-oxo-8-(1-phenylpyrrolidin-2-yl)-4H-chromene-6-carboxylic acid (87 mg, 86%) which was used without further purification. Mass Spectrum: m/z [M+H]+=435.
