Procedure

The product of above-mentioned (10-a) (0.23 g, 0.69 mmol) was added into a mixed solvent of methylene chloride (3.5 ml) and trifluoroacetic acid (1.4 ml), and triethylsilane (0.15 ml, 0.96 mmol) was added dropwise thereto, followed by stirring at 25° C. for 2 hrs. The reaction solution was added into 1N aqueous K2CO3 solution, and extracted with ethyl acetate. The organic layer was concentrated under reduced pressure, and the residue was purified by silica gel chromatography (chloroform:acetone=5:1) to give 91 mg of 5,6-dimethyl-3-hexylidene-2-(3-pyridyl)isoindolin-1-one.
