CODEN: EPXXDW. CLASS: IC: C07D317-58. APPLICATION: EP 83-102199 6 Mar 1983. PRIORITY: IT 82-20442 29 Mar 1982. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) The title compd. (fipexide), useful as an antidepressant and central nervous system stimulant (no data), was prepd. Thus, 4-ClC6H4OCH2CO2H was converted to 4ClC6H4OCH2COCl, which was added to 1-piperonylpiperazine in CHCl3, and the mixt. was heated to give fipexide hydrochloride. .

DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Section cross-reference(s): 5, 23, 28 RCMe2COR1 [R = CHO or deriv.; R1 = haloalkyl, (un)substituted Ph, PhO, etc.] were prepd. and used as intermediates for prepn. of azolyl derivs. for use as agricultural fungicides. Thus, 210 g 1-morpholinoisobutene were added over 1 h to 169.0 g ClCH2COCl in 350 mL Et2O at 5° and the mixt. stirred 3 h under reflux to give ClCH2COCMe2CHO, which was used for prepn. of the fungicidal tetrazolyl alc. I. Also prepd. were, e.g., 2,4-Cl2C6H3OCH2COCMe2CHO and 2-ClC6H4COCMe2CHO. .
