Procedure
46 μl of pyridine and 85 mg of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride were added to 31 μl of acrylic acid dissolved in 3 ml of THF at 0° C., reacted with 100 mg of the compound (132-1) of Example 132 for 30 mins, and stirred for 2 hours while heating to room temperature. The reacted solution was extracted with 6 ml of ethylacetate 3 times after adding 4 ml of water, dried over anhydrous magnesium sulfate, filtered and distilled under a reduced pressure, and the resulting residue was subjected to column chromatography (eluent-chloroform:methanol=15:1) to obtain the title compound (20 mg, 18%).
