Procedure
Di-tert-butyl 2-(tert-butyldimethylsilyloxy)propane-1,3-diylbis (methylcarbamate) (21 g, 48.6 mmol) was dissolved into 200 ml methanol at 0° C. Concentrated HCl (4 mL) was added dropwise and the reaction mixture was stirred at RT for 6 hrs. The mixture was placed over an ice water bath and 10 g of NaHCO3 was added slowly. Then the reaction mixture was dried with MgSO4, and then filtered. The filtrate was concentrated to yield 15.0 g of di-tert-butyl 2-hydroxypropane-1,3-diylbis(methylcarbamate) (97%).
