Procedure

The product of step (f) (375 mg, 1.23 mmol) was dissolved in 4 mL dioxane and treated with Me2Zn (1.25 mL of 2M in toluene) and Pd(dppf)2Cl2. After heating to 100° C. for 3h, the reaction was cooled, quenched with water, filtered through silica gel (washing with EtOAc), and concentrated to give 337 mg of the sub-title compound as an oil.
