Phenolate Sodium → HCID 13060092, compound

Participants

Reaction Steps

g of 3-methyl-6-chloromethyl-imidazo-(2,1-b)thiazole hydrochloride, prepared as described in Example 27, is introduced with stirring into a cooled solution of 3.5 g of sodium phenate in 100 ml of THF. After about 1 hour the sodium chloride which precipitates is filtered off, the solvent is evaporated and acidic water is added to the residue. The aqueous solution is extracted, at pH 3-6, with chloroform. The pH is then raised to 7-7.5 and the aqueous solution is again extracted with chloroform. This extract is dried and the solvent is then evaporated to yield 4 g of 3-methyl-6-phenoxymethylimidazo-(2,1-b)thiazole; m.p. 190°-192° (methyl-ethyl-ketone).
