Reaction Steps

Following a procedure analogous to that for the synthesis of Compound D of Example 22, (S)-1-tert-butyl 2-methyl 4-(((trifluoromethyl)sulfonyl)oxy)-1H-pyrrole-1,2(2H,5H)-dicarboxylate (585 mg, 1.56 mmol) and (S)-2-tert-butyl 3-methyl 7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3,4-dihydroisoquinoline-2,3(1H)-dicarboxylate (650 mg, 1.56 mmol) were converted to the title compound (563 mg, 70%). MS (ESI+) m/z 517.4 (M+H)+.
