Reaction Steps
The product from step 1 (3.0 g, 16.07 mmol) was added to a suspension of sodium hydride (964.3 mg, 32.14 mmol) in DMF at 0° C. After 5 min 4-iodo-tetrahydro-pyran (3.41 g, 16.07 mmol) was added and the reaction mixture was stirred at RT for 1 h. The reaction mixture was quenched with water at 0° C. and neutralized with trifluoroacetic acid. Evaporation and purification of the crude product by silica gel chromatography using ethyl acetate/n-heptane gave the desired product (1.385 g, 32%)
