A solution of the product from step e) (2.4 g, 6.89 mmol) in dioxane (34.5 ml) was treated with Pd(dppf)2Cl2 (337 mg, 0.41 mmol) and a 2M solution of dimethylzinc in toluene (6.89 ml, 13.78 mmol) at 102° C. for 1 hour. The reaction was cooled to 22° C. and carefully quenched with sat. NH4Cl (20 ml). After the effervescence subsided, the reaction was extracted with EtOAc (3×50 ml). The combined organic layers were dried (MgSO4) and passed through a plug of silica-gel using 50:50 hexanes:EtOAc to give the subtitle compound (1.9 g, 97%). MS calculated for C17H17NOS+H 284, observed 284.
