Vorschrift

Suspended into 135 mL of toluene was 18.0 g of the carboxylic acid (26) obtained in Synthesis Example 1-1-2, and then into the resulting suspension was gradually added 10.3 g of oxalyl chloride at 80° C. After this mixture was stirred for 4 hours, toluene was removed by distillation under reduced pressure to obtain the intended product. The obtained acid chloride was used in the next reaction without further purification.
