実験手順
The above reaction mixture from Example 15 was cooled below 5° C. and was added with 20% of HCl IPA solution until pH 1˜4. The mixture was stirred for additional 1 h and was filtered. The filter cake was washed with 34.6 kg of dichloromethane. Desired crude product was obtained. The overall yield from Example 12 was 67% and the purity was 97%. The crude product was recrystallized with methanol/dichloromethane/MTBE to give the desired pure product.
