Reaction Conditions:
with sodium hydride in N,N-dimethyl-formamide at 0 - 20; for 12 h;
Steps:
1
After dissolving 102.41g (655.54mmol) of Intermediate 22-13 and 82.73g (655.54mmol) of Intermediate 22-14 in 1L of DMF, an ice bath was installed to maintain 0 and NaH (60%) 26.22g (655.54mmol) was added dropwise. I did. After raising the temperature to room temperature and stirring for 12 hours, after confirming the reaction, 1L of 1N HCl was added and stirred. After extraction by adding 1 L of PE, distillation and column to give 69.72 g of intermediate 22-15 in a yield of 45%.
