Cinnanienyl-acetyl-isoxazol is insoluble in water and potash, readily soluble 

 in alcohol or ether, and somewhat less so in petroleum ether. It crystallizes 

 from alcohol in pearly plates, and from petroleum ether in colourless needles.

8T6 grms. of acetophenone were mixed with 105 p 6 grms. of ethyl cinnamate, 

 and some ligroin was added as a solvent. During the course of several hours 

 48-6 grms. of sodamide, finely powdered under ligroin (or an equivalent 

 quantity of metallic sodium), were added. The treatment adopted was 

 similar to that employed in the case of cinnamyl-acetyl-methane described 

 above, and a yield of about 10 grms. of a light yellow crystalline substance 

 was obtained. It was recrystallized from methyl alcohol M.P. 109° C. 



0171 2 substance gave 0-5126 C0 2 , and 0-0896 H 2 0, 

 corresponding to C 81 - 6, H 5 - 8.

 Cinnamyl-benzoyl-methane crystallizes in long needles, very soluble in ether, 

 chloroform, or alcohol; less so in methyl alcohol or ligroin. Its alcoholic 

 solution is coloured a greenish brown by ferric chloride. The crystals are 

 coloured red by concentrated sulphuric acid, and gradually dissolve in it to a 

 yellow solution. It colours wool mordanted with iron a reddish brown, and 

 with chromium a dark yellow.

A solution of 2-3 grms. of cinnamyl-benzoyl-methane and 3 grms. of 

 hydroxylamine hydrochloride in absolute alcohol was heated under a reflux 

 condenser for about 6 hours. When the alcohol had been distilled off and 

 the ethereal extract washed with water and dilute potash, about 2 grms. 

 of a solid were obtained, which, when recrystallized from alcohol, melted at 

 137-138° C. 



0-2044 substance gave 0-6164 C0 2 , and 0-1019 L1 2 ; 01815 substance 

 gave 9-2 c.c. N at 15° C. and 750° mm.p.,

 Cinnamenyl-phenyl-isoxazol crystallizes in small, colourless needles in- 

 soluble in potash, sparingly soluble in ligroin, and readily soluble in alcohol.
