(S)-3-((tert-butyldimethylsilyloxy)methyl)-1,2,3,4-tetrahydroisoquinoline → Methyl 3-((S)-3-((tert-butyldimethylsilyloxy)methyl)-1,2,3,4-tetrahydroisoquinoline-2-carbonyl)-4-(4-(dibutylcarbamoyl)-1-methyl-1H-imidazol-2-yl)benzoate

Participants

Reaction Steps

Following a procedure analogous to that for the synthesis of Intermediate 271H, 2-(4-(dibutylcarbamoyl)-1-methyl-1H-imidazol-2-yl)-5-(methoxycarbonyl)benzoic acid (Intermediate 281B, 170 mg, 0.42 mmol) and (S)-3-((tert-butyldimethylsilyloxy)methyl)-1,2,3,4-tetrahydroisoquinoline (237 mg, 0.85 mmol) were converted to the title compound (248 mg, 87%). MS(ESI+) m/z 675 (M+H)+.
