Intermediate 98 (1.48 g, 5.73 mmol) in dioxane (50 ml) was stirred under argon. DIPEA (2 ml, 11.47 mmol), xantphos (0.2 g, 0.34 mmol) and Pd2(dba)3 (0.157 g, 0.17 mmol) were added and the reaction was heated to 100° C. Phenyl-methanethiol (0.64 ml, 5.45 mmol) was slowly added and the reaction stirred for 1 h. The reaction was quenched by the addition of 50 ml of H2O. After extraction with ethyl acetate (three times) the combined organic layers were washed with water, dried with Na2SO4, evaporated to dryness and the product was purified by silica gel chromatography.
