| Hazard Information | Back Directory | [Uses]
1-Trimethylsilylmethanol is used as nucleophile to resolve the racemate obtained from enantioselective esterification of naproxen (2-(6-methoxy-2-naphthyl) propionic acid) by lipases. It was also used as a nucleophilic hydroxymethylation agent. | [Purification Methods]
If the NMR indicates impurities (should have only two signals), then dissolve it in Et2O, shake this with aqueous 5N NaOH, M H2SO4, saturated aqueous NaCl, dry (MgSO4) and distil it using an efficient column at atmospheric pressure. The 3,5-dinitrobenzoate has m 70-70.5o (from 95% EtOH). [Huang & Wang Acta Chem Sin 23 291 1957, cf. Chem Abstr 52 19911 1958, Speier et al. J Am Chem Soc 81 1844 1959 and Speier et al.
