This oxiiu is ol)t;iiii'_'d by boiling a luivlure of one niokcnle (1 gr. ) of 

 the /^'j-Leto-R-liexeiie d'jrivativo willi tlircc mol'.cules (.oBgr. ) of hvdroxyl- 

 aniiic livdrcchloride and one and one-half molecules (.56 gr. ) of sodium 

 carbouale dissolved in ethyl alcohol (140cc. ) for forty-five minutes, using 

 a return condenser. Ono-lialf of tlie alcohol is distilled off and tlie residue 

 on cooling d( posits white crystals, which, when they have been recrystal- 

 lized from a mixture of benzene and ligroin, melt at 221-3°. Tlie sub- 

 stance is easily sokible in liot alcohol, cold ether, acetic acid, and ii()t ben 

 zenc, but very sparingly soluble in hot ligroin (40-()0^).

This body is prepared by boiling th" ■j-keto-R-hexene derivative witli 

 excc ss of eitlier acetic anhydride or acetyl cidoride for thirty mini.t( s. The 

 mixture assumes a yellowish-red tint, and yields a solid substance only 

 when it is poured into a large excess of water. The white amorphous mass 

 recrystallizes from liot ligroin (40-00") in bunches of long needles, melting 

 at 98°. It is soluble in cold glacial acL'ticacid, benzene, ether and alcohol, 

 but is sparingly soluble in ligroin.
