Versuchsvorschrift

HATU (92 mg, 0.24 mmol) was added to a solution of (R)—N-(3,5-difluoro-4-(trimethylsilyl)phenyl)-6-methoxy-1,2,3,4-tetrahydroisoquinoline-1-carboxamide (86 mg, 0.22 mmol), cis-3-(2-(tert-butoxy)-2-oxoethyl)cyclobutanecarboxylic acid (51.9 mg, 0.24 mmol) and DIEA (0.043 mL, 0.24 mmol) in DMF (2 mL) at room temperature, and the mixture was stirred overnight at room temperature. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (solvent gradient; 3→50% ethyl acetate/hexane) to give tert-butyl 2-(cis-3-((R)-1-((3,5-difluoro-4-(trimethylsilyl)phenyl)carbamoyl)-6-methoxy-1,2,3,4-tetrahydroisoquinoline-2-carbonyl)cyclobutyl)acetate (86 mg, 0.22 mmol) as a colorless oil.
