Versuchsvorschrift

HATU (90 mg, 0.24 mmol) was added to a solution of (R)-6-ethoxy-N-(4-(1-ethoxy-2-methylpropan-2-yl)-3,5-difluorophenyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxamide hydrochloride (101 mg, 0.22 mmol), cis-3-(2-(tert-butoxy)-2-oxoethyl)cyclobutanecarboxylic acid (50.8 mg, 0.24 mmol) and DIEA (0.085 mL, 0.47 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 washed with brine, and 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)-6-ethoxy-1-((4-(1-ethoxy-2-methylpropan-2-yl)-3,5-difluorophenyl)carbamoyl)-1,2,3,4-tetrahydroisoquinoline-2-carbonyl)cyclobutyl)acetate (135 mg, 0.215 mmol, quant.).
