Reaction Steps

Phosphorus oxychloride (5.68 mL) was added dropwise to a cooled (0° C.) solution of EXAMPLE 391D (18.37 g) in N,N-dimethylformamide (20 mL) and dichloromethane (80 mL). The mixture was then stirred overnight before it was diluted with ethyl acetate (600 mL) and washed with aqueous sodium acetate, water (3×), and brine and dried over Na2SO4. After filtration and concentration, the crude product was used directly in the next reaction without further purification.
