Procedure

A mixture of the protected glycerol derivative Compound 41 (5.0 g, 16 mmol) and 10% palladium on activated carbon (wet Degussa type E101 NE/W) (0.43 g) in MeOH (50 mL) was evacuated using an aspirator pump and filled with hydrogen. After 2 hours, TLC analysis showed the reaction to be complete, the mixture was filtered through Celite and the filtrate was evaporated to dryness to give 1-O-t-butyldimethylsilyl-2-O-methyl-rac-glycerol (Compound 42) (99%) as a colourless oil.
