Reaction Steps

To a solution of the product from Step 1 (470 mg, 1.68 mmol) in toluene (15 mL) at -65° C. there was slowly added 1.0M DIBAL in toluene (2.24 mL, 2.24 mmol) and the mixture was stirred at -65° C. for 1 hour. There was slowly added MeOH (5 mL) and the mixture was then allowed to warm up to r.t. There was added H2O (20 mL) and 1N aqueous HCl (10 mL) and after shaking the organic phase was washed with H2O, dried over MgSO4 and evaporated down to an oily residue which was taken as such to the next step.
