Procedure

Phosphorus oxychloride (3.45 mL) was added dropwise to a cooled (0° C.) solution of EXAMPLE 314A (4.2 g) in N,N-dimethylformamide (12 mL) and dichloromethane (30 mL). The mixture was then stirred at room temperature overnight before it was diluted with ethyl acetate (300 mL) and washed with aqueous sodium acetate, water (3×), brine and dried over Na2SO4. After filtration and concentration, the crude product was used directly in the next reaction without further purification.
