Procedure

To a solution of the product from Step A (0.5 g) in dimethylformamide (20 mL) was added hydroxybenzotriazole (0.37 g), EDC (0.51 g), N-methylmorpholine 0.8 mL), and (S) methione methyl ester hydrochloride (0.49 g). After stirring for 16 h the solution was concentrated in vacuo and the residue was partitioned with water and ethyl acetate. The ethyl acetate layer was washed with saturated sodium hydrogen carbonate, 2% potassium hydrogen sulfate and saturated sodium chloride, dried over magnesium sulfate, and concentrated in vacuo to yield the title compound.
