Adding a certain compound to certain chemical reactions, such as: 184177-83-1, name is 1-((2S,3S)-2-(Benzyloxy)pentan-3-yl)-4-(4-(4-(4-hydroxyphenyl)piperazin-1-yl)phenyl)-1H-1,2,4-triazol-5(4H)-one, belongs to Triazoles compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 184177-83-1, 184177-83-1
10 g of compound of formula A and 76 mL DMSO were added into a reaction flask at room temperature, and stirred until clarification. An alkaline solution previously prepared from 1.4 g sodium hydroxide and 6 g water was further added thereto. The mixture was stirred for 1 h. Then, 10 g of compound of formula IX was added thereto. The mixture was warmed up to 38 C. and reacted for 16 h. After the reaction was completed, the mixture was warmed up to 45 C. 6 mL water was added thereto. The mixture was stirred for 30-60 min. 154 mL water was further added thereto. The mixture was stirred for 1 h, and filtered under suction. The resultant solid was drip washed with 4¡Á50 mL purified water to obtain a wet product. (0249) The wet product and 60 mL of 90% aqueous ethanol solution were added to a reaction flask, warmed up to 65 C., and stirred. After clarification, 1.5 g active carbon was added thereto. The mixture was stirred for 15 min, filter-pressed while hot, and washed with 15 mL of 90% aqueous ethanol solution. Then, the filtrate was warmed up to 65 C., stirred, cooled to 40-45 C. after clarification, crystallized while keeping the temperature for 1 h, further cooled to 0-5 C., crystallized while keeping the temperature for 1 h, and filtered under suction. The resultant solid was first drip washed with 5 mL of 50% aqueous ethanol solution, and then drip washed with 4¡Á50 mL purified water. The solid was collected, placed in a ventilated oven at 50-55 C. and dried for 16 h to obtain 13.2 g of product.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-((2S,3S)-2-(Benzyloxy)pentan-3-yl)-4-(4-(4-(4-hydroxyphenyl)piperazin-1-yl)phenyl)-1H-1,2,4-triazol-5(4H)-one, other downstream synthetic routes, hurry up and to see.
