Procedure
The above reaction mixture from Example 14 was cooled to 5-10° C. and was added with 20% of HCl IPA solution until pH 2˜3. The mixture was stirred for additional 1 h and was filtered. The filter cake was washed with 140 mL of dichloromethane. 12.2 g of desired crude product were obtained. The overall yield from Example 11 was 71.1% and the purity was 97%. The crude product was recrystallized with methanol/dichloromethane/MTBE to give the desired pure product:
