Reaction Steps
To a solution of the alcohol of step A (0.81 g, 4.0 mmol), benzoic acid (0.74 g, 6.0 mmol) and triphenylphosphine (2.11 g, 8.0 mmol) in toluene (20 mL) was added DIAD (1.67 mL, 8.0 mmol). After being stirred at room temperature for 4 hours, the solution was concentrated. The residue was purified by flash chromatography eluting with 0%, 5% and 20% EtOAc/hexanes provided 1.0 g of the title compound. MS calculated (M+H)+ 308. found 308.1.
