Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 126352-69-0, name is 4,5,6,7-Tetrahydropyrazolo[1,5-a]pyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
(2) To acetic anhydride (0.153 ml) was added formic acid (0.077 ml) at 15-20 C. The mixture was stirred at ambient temperature for 30 minutes. To this solution was added 4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine (100 mg) under ice-cooling and the mixture was stirred at the same temperature for 1 hour. The reaction mixture was added to a mixture of dichloromethane and aqueous sodium bicarbonate solution. The separated organic layer was dried over magnesium sulfate and evaporated in vacuo to give 4-formyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine (79.9 mg). IR (Nujol): 1670, 1535, 1500, 1450, 1430, 1400 cm-1. NMR (DMSO-d6, delta): 1.97-2.27 (2H, m), 3.62-3.91 (2H, m), 3.97-4.24 (2H, m), 6.22 and 6.48 (1H, each d, J=3 Hz), 7.29 (1H, d, J=3 Hz), 8.19 and 8.77 (1H, each s).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 126352-69-0, 4,5,6,7-Tetrahydropyrazolo[1,5-a]pyrimidine.
