Procedure

Aqueous ammonium hydroxide (25%; 10 g, 150 mMol) and 40 mL of ethanol were charged to a 100 mL RB flask equipped with a magnetic stirrer. The mixture was stirred and heated to 50° C. 2-{3-[Dimethyl-(2-trimethylsilanyl-ethyl)-silanyl]-propoxymethyl}-oxirane 8 (2 g; 7.28 mMol) mixed with 10 g ethanol was placed in an addition funnel and added dropwise to the flask. The mixture was stirred and maintained at 50° C. for an additional 8 hours. Ethanol and water were stripped off on the rotovap. The mixture was distilled under vacuum to remove impurities.
