Reaction Steps

Following a procedure analogous to that for the synthesis of Example 303, 2-(2-(dibutylamino)pyrimidin-4-yl)-5-(naphthalen-2-ylsulfonylcarbamoyl)benzoic acid (Intermediate 303E, 25 mg, 0.05 mmol) was reacted with ((S)-3-(azidomethyl)-1,2,3,4-tetrahydroisoquinoline (Intermediate 92A, 11 mg, 0.06 mmol) and provided a crude oil which was dissolved in THF (1.1 mL). PPh3 (10 mg, 0.014 mmol) was added followed by aq. 0.5N NaOH (100 μL). The resulting reaction mixture was stirred at 50° C. for 1.5 h and then neutralized with 1N HCl solution (100 μL). The volatiles were removed in vacuo, and the residue was purified by preparative HPLC to give the title compound (5 mg, 52%). MS(ESI+) m/z 705.2 (M+H)+.
