    • PURPOSE: A novel method for preparing antiulcerants, Sofal-cone represented by the formula 1 is provided, to obtain Sofal-cone in high purity and high yield without using unstable and toxic ethylbromo acetate. CONSTITUTION: The method comprises the steps of reacting 4-(3-methyl-2-butenyloxy)benzaldehyde represented by the formula 2 with 2-cyanomethoxy-4-(3-methyl-2-butenyloxy)acetophenone represented by the formula 3 by using hydrochloric acid gas in a solvent to obtain Sofal-cone of the formula 1. Preferably the solvent is selected from the group consisting of acetone, acetone aqueous solution, and ethanol aqueous solution. The equivalence of hydrochloric acid gas is 1-10 based on the Sofal-cone by weight. Preferably the reaction is carried out at a temperature of 10-150 deg.C 0.5-8 hours, and more preferably at a temperature of 20-50 deg.C for 2 hours.
    • 目的:提供一种制备抗溃疡的新方法,由式1表示的沙锥,以高纯度和高产率获得Sofal-cone,而不使用不稳定和有毒的乙基溴乙酸酯。 方案:该方法包括使由式2表示的4-(3-甲基-2-丁烯氧基)苯甲醛与由式3表示的2-氰基甲氧基-4-(3-甲基-2-丁烯氧基)苯乙酮通过使用 在溶剂中加入盐酸气体得到式1的沙耳锥。优选的溶剂选自丙酮,丙酮水溶液和乙醇水溶液。 盐酸气体的重量相当于以重量计的Sofal-cone。 优选地,反应在10-150℃,0.5-8小时,更优选在20-50℃的温度下进行2小时。
