Reaction Steps

Methyl (R)-(−)-3-hydroxy-2-methylpropionate (0.82 g, 6.92 mmol) (Aldrich) was dissolved in dichloromethane (8 mL, dried over molecular sieves). Imidazole (0.67 g, 9.68 mmol) (Aldrich) was added. When all had dissolved, tert-butyldiphenysilyl chloride (1.80 mL, 6.92 mmol) (Aldrich) was added and the mixture was stirred at ambient temperature for 3 hours. The reaction was diluted with additional dichloromethane, washed with water and brine, dried over anhydrous sodium sulfate and concentrated to give methyl (R)-3-(tert-butyl-diphenyl-silanyloxy)-2-methyl-propionate as an oil. (Yield 2.42 g, 98%).
