, (2020/06/02)
The invention belongs to the field, of medicine synthesis, and particularly relates to a synthesis method III of tirofiban hydrochloride intermediate. by, reduction of an intermediate I under the action of a sodium borohydride reducing system to obtain intermediate II, intermediate II under Lewis acid chloride in the presence. SOCl2 Reaction conditions of, process are mild III, and N - process operation is simple, the reaction conditions of the reaction yield, product are improved, the product purity is high, and the reaction yield is increased by, times without being subjected to column purification, to improve the clinical medication safety, of the injection using, the standard crude drug product of the pharmacopoeia standard, and is suitable, for industrial production.

A compound of the formula (I) wherein A is O, S, CHR1or NR2, R1and R2are H, lower alkyl, X1and X2are H, halogen, nitro, cyano, etc., Y1is H, lower alkyl, Z1and Z2are H, halogen, cyano, hydroxy, lower alkyl, etc., and n is an integer of 2 to 4, a pharmaceutically acceptable salt thereof, a process for preparing the same, a pharmaceutical composition containing the same as an active ingredient, and an intermediate therefor. The compounds (I) of the present invention show a potent PDE IV inhibitory activity as well as an excellent bronchodilating activity, and hence, they are widely useful as a PDE IV inhibitor in the treatment or prophylaxis of allergic inflammatory diseases or organ inflammatory diseases, especially in the treatment or prophylaxis of pulmonary diseases accompanied by airway obstruction such as asthma.
