Procedure

Phosphorus oxychloride (2.33 mL) was added dropwise to a cooled (0° C.) solution of EXAMPLE 265D (7.5 g) in N,N-dimethylformamide (10 mL) and dichloromethane (30 mL). The mixture was then stirred overnight before it was diluted with ethyl acetate (300 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.
