Participants

Reaction Steps

A solution of N-[(1S)-2-[3-bromo-4-(1,1-dioxido-3-oxoisothiazolidin-5-yl)phenyl]-1-(5-phenyl-1H-imidazol-2-yl)ethyl]benzenesulfonamide trifluoroacetate (3.5 mg, 4.8 μmol), zinc cyanide (1.7 mg, 14 μmol), tetrakis(triphenylphosphine)palladium(0) (1.11 mg, 960 nmol) and N,N-dimethylformamide (1.5 mL) was heated at 175° C. for 4 min in the microwave. The reaction filtered, concentrated in vacuo and purified by preparative LCMS to yield the desired product (2.0 mg, 60%). 1H NMR (400 MHz, CD3OD): δ 7.8–7.3 (m, 13H), 5.3–5.0 (m, 2H), 3.5–3.4 (m, 2H), 3.3–3.2 (m, 2H); MF=C29H24F3N5O7S2; LCMS found for C27H24N5O5S2(M+H)+: m/z=562.
