実験手順

A solution of 4-(4-amino-3-bromo-phenyl)-1,1-dioxo-hexahydro-1λ6-thiopyran-4-carbonitrile (109 mg, 0.332 mmol, as prepared in the previous step) in DMF (4 mL) was treated with 2-(4,4-dimethyl-cyclohex-1-enyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (94.1 mg, 0.398 mmol) and aq Na2CO3 (1.32 mL, 2.66 mmol, 2.0 M). The mixture was degassed via sonication, placed under Ar, treated with Pd(dppf)Cl2 (24.3 mg, 0.034 mmol), and heated to 60° C. for 24 h. The cooled mixture was diluted with EtOAc and water. The aqueous layer was extracted with EtOAc (4×). The combined organic layers were dried over MgSO4 and concentrated in vacuo. Purification of the residue by silica gel chromatography on a 10-g Isolute SPE column (FlashMaster system) with 25% EtOAc-hexane afforded the title compound (119 mg, 100%) as a white solid. Mass spectrum (ESI, m/z): Calcd. for C20H26N2O2S, 359.2 (M+H). found 359.3.
