Participants

Reaction Steps

A mixture of Example 68A (250 mg, 0.95 mmol), 2-(4-morpholinyl)ethanol (0.19 mL) and triphenylphosphine on resin (630 mg, 3 mmol/g, 1.9 mmol) in THF (5 mL) was treated with DEAD (0.179 mL) and stirred at room temperature for about 18 hours. The mixture was filtered and the filtrate was concentrated. The residue was purified twice by flash column chromatography on silica gel, first eluting with 5% methanol/dichloromethane then with 50% ethyl acetate/hexanes to provide 180 mg of the desired product. MS (ESI(+)) m/e 377 (M+H)+.
