실험 절차

Compound 30 (calculated assuming that Compound 9 in the previous process was 74.74 g and the yield of amidation was 80%) was dissolved in chloroform (140 mL). The solution was added to a 6N aqueous HCl solution (530 mL) at room temperature (20 to 30° C.). The equipment used to add compound 30 was thoroughly washed with chloroform (240 mL) and was then stirred at room temperature (20 to 30° C.) for 2.5 hours. After the chloroform layer was separated, chloroform (300 mL) was added to the aqueous layer. While ice (740.7 g in total) was added as necessary, a 4N aqueous sodium hydroxide solution (805 mL) was added portionwise. An additional amount of 4N aqueous sodium hydroxide solution (25 mL to adjust the pH of the aqueous layer to 8.5) was added, followed by the addition of chloroform (80 mL), and separation was performed. After the chloroform layer was separated, chloroform (200 mL) was added to the aqueous layer and separation was performed again. The chloroform layer collected in the two extraction processes was dried over magnesium sulfate and suction-filtered. The filtrate was then evaporated under reduced pressure to give 100.15 g (103.9% yield, in 2 steps) of the crude desired product as a pale yellow solid.
