Research on the manufacture of hustazol

Research on the manufacture of hustazol. Study on the optimum condition of reduction reaction. (Peking Pharmaceutical Works, Peking, Peop. R. 119-56-2 and 134-85-0 are also occured in this study. China). Hua Hsueh Tung Pao, (5), 287-9, 298 (Chinese) 1976. CODEN: HHTPAU. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 25 During the manuf. of hustazol (I) optimum conditions for the crit. step of redn. of p-ClC6H4COPh (II) to p-ClC6H4CH(OH)Ph (III) by Zn in NaOH were studied. Addn. of 1 mole powd. Zn to 1.4 mole II at 110.degree. in 1.5 h and keeping the temp. at 120-5.degree. for 5 h gave >94% III of >96% purity. .
