Methyl 4-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)-3-(1,2,3,4-tetrahydroisoquinoline-2-carbonyl)benzoate → Methyl 4-(4-(dibutylcarbamoyl)-1-methyl-1H-imidazol-5-yl)-3-(1,2,3,4-tetrahydroisoquinoline-2-carbonyl)benzoate

Participants

Reaction Steps

Following a procedure analogous to that for the synthesis of Intermediate 264I, 5-bromo-N,N-dibutyl-1-methyl-1H-imidazole-4-carboxamide (600 mg, 1.9 mmol) and methyl 4-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)-3-(1,2,3,4-tetrahydroisoquinoline-2-carbonyl)benzoate (Intermediate 264H, 1.55 g, 3.8 mmol) were converted to the title compound (400 mg, 40%). MS(ESI+) m/z 531.6 (M+H)+.
