Procedure

To a stirred solution of 3-(tert-butyldimethylsilyloxy)cyclobutyl pivalate (4.32 g, 15 mmol) in THF (20 ml) at 0° C. was added diisobutylaluminum hydride, 1.0 m solution in hexanes (48 ml, 48 mmol) dropwise. The reaction was stirred in 1 h, then slowly quenched with Rochelle's salt. The quenched mixture was stirred and layers were separated. The organic layer was dried over MgSO4 and concentrated to give the title compound as a colorless oil.
