Description

S Process for preparing la This invention provides a process for the tion of new of the general formula in whi group and is a halogen The novel compounds of formula I above are described and claimed in our copending Patent Application The process according to the present invention alkanolamino comprises heating a derivative of the general in which Rg and X have the same meaning as in formula I in presence of a catalyst to effect a Fries rearrangement of the compound of formula II to the corresponding compound of formula In formulae I and II the alkanoyl group may for butyryl or As alkanoyl the group there may be exemplified a residue of phatic acid such as 2735 Examples of the halogen atom X include chlorine As the in the process according to the there may be used the one usually employed for the Fried rearrangement such as zinc aluminum chloride iron chloride tin chloride aluminum bromide bismuth chloride titanium chloride antimony hydrogen hydrogen boron trifluoride or phosphorus pentachloride The present reaction can proceed without any but there may be employed a solvent inert to the reaction such as carbon disulfide carbon tetrachloride nitrobenzene benzene or alkanoyl The thus obtained phenols are novel and useful as intermediates for the production of pharmaceuticals having marked pharmacological activities such as narcotic and for e The following example is shown for illustration of this Example 1 To a suspension of 22 g of anhydrous aluminum chloride in 20 ml of carbon there are added 25 g of acetate and the resulting mixture is heated in an oil After the carbon fide is removed by the resulting mixture is heated at for 4 After the reaction is the reaction mixture is mixed with 10 aqueous solution of hydrochloric acid and extracted with ethyl The extract is washed with dried and concentrated to give 0 g of acetophenone as white crystals melting at 207 to for 6 insufficientOCRQuality
