Temperature: 80 °C

Procedure

A solution of 40.0 mg (0.114 mmol) of 2-bromo-4-[2-(morpholine-4-sulfonyl)-ethyl]-phenylamine (as prepared Example 26, step (e)) in toluene (4 mL) and EtOH (2 mL) was treated with 458 μL (0.229 mmol) of 2.0 M aqueous Na2CO3 and 29.8 mg (0.226 mmol) of 4,4-dimethyl-cyclohex-1-enylboronic acid. The mixture was degassed via sonication, placed under Ar, treated with 13.2 mg (0.0110 mmol) of Pd(PPh3)4, and heated to 80° C. for 5 h. The mixture was cooled to RT, diluted with EtOAc (10 mL), and washed with saturated aqueous NaHCO3 (1×10 mL) and brine (1×10 mL). The organic layer was dried (MgSO4) and concentrated in vacuo to afford 60.0 mg of the title compound as a tan solid: Mass spectrum (ESI, m/z): Calcd. for C20H30N2O3S, 379.2 (M+H). found 379.1.
