The yellow filtrate, obtained by passing through a membrane filter (JV 0.1 μm), was added dropwise to 300 mL of 1 : 2 mixed solution of ethanol/diethyl ether, giving a yellow oil, which was rinsed three times with 150 mL of the 1 : 2 mixed solution of ethanol/diethyl ether. The yellow oil was dissolved in 5 mL water, followed by adding 500 mL methanol. After filtration of the yellow solution through a membrane filter (JV 0.1 μm), the filtrate in a sealed flask was allowed to stand for 10 days at room temperature. After one day, pale yellow needle crystals began to form. After 10 days, the crystals collected on a membrane filter (JG 0.2 μm) were washed with (50 mL × 2) methanol and (50 mL × 2) diethyl ether, thoroughly dried by suction and then dried in vacuo for 2 h. The light-and thermally-stable yellow powder of 1a obtained in 6.01 g (84.2%) yield was hygroscopic and soluble in water, but insoluble in most organic solvents. From similar work-up, the sodium salt 1b was obtained in 145 g (49.0%) yield.
