Participants

Reaction Steps

HATU (55.7 mg, 0.15 mmol) was added to a solution of (R)—N-(3,5-difluoro-4-(trimethylsilyl)phenyl)-6-methoxy-1,2,3,4-tetrahydroisoquinoline-1-carboxamide (52 mg, 0.13 mmol), trans-3-(2-(tert-butoxy)-2-oxoethyl)cyclobutanecarboxylic acid (30.0 mg, 0.14 mmol) and DIEA (0.026 mL, 0.15 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 precipitate was collected by filtration, and washed with water to give tert-butyl 2-(trans-3-((R)-1-((3,5-difluoro-4-(trimethylsilyl)phenyl)carbamoyl)-6-methoxy-1,2,3,4-tetrahydroisoquinoline-2-carbonyl)cyclobutyl)acetate (64.0 mg, 0.109 mmol, 82%) as a white solid.
