Versuchsvorschrift

Into a round-bottom flask, was placed a solution of 4-cyclobutyl-5-formyl-2-methylbenzoic acid (compound 392.1, 490 mg, 1.57 mmol, 1.00 equiv, 70%) in N,N-dimethylformamide (8 mL). Compound 1.5 (500 mg, 1.57 mmol, 1.00 equiv), EDC.HCl (860 mg, 4.26 mmol, 2.00 equiv, 95%) and 4-dimethylaminopyridine (550 mg, 4.28 mmol, 2.00 equiv, 95%) were added to the reaction mixture. The resulting solution was stirred overnight at room temperature, and then diluted with 30 mL of ethyl acetate. The resulting mixture was washed with 4×30 mL of brine, then dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified using silica gel column chromatography with ethyl acetate/petroleum ether (1:2) as eluent to yield 560 mg (74%) of the title compound as a white solid.
