Procedure

A mixture of HATU (100 mg, 0.26 mmol), (R)—N-(7-fluoro-1,1-dimethyl-2,3-dihydro-1H-inden-5-yl)-6-(methoxymethyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxamide hydrochloride (100 mg, 0.24 mmol), cis-3-(2-(tert-butoxy)-2-oxoethyl)cyclobutanecarboxylic acid (56.3 mg, 0.26 mmol), DIEA (0.094 mL, 0.53 mmol) and DMF (2 mL) 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-((7-fluoro-1,1-dimethyl-2,3-dihydro-1H-inden-5-yl)carbamoyl)-6-(methoxymethyl)-1,2,3,4-tetrahydroisoquinoline-2-carbonyl)cyclobutyl)acetate (130 mg, 0.225 mmol, 94%) as a colorless oil.
