The compound 26-2 (30 mg) prepared in Step 2 was dissolved in toluene (4 ml) and to the solution was added 4-t-butylbenzylamine (150 μl), followed by refluxing for 3 hours. The resulting mixture was concentrated under reduced pressure and the obtained residue was chromatographed on silica gel column (ethyl acetate/hexane=1/1) to yield the compound 26-3 (28 mg, 58%).
