Application of 23002-51-9, The major producers of chemicals have been the Europe, Japan and China. 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 23002-51-9, name is 6-Chloro-1H-pyrazolo[3,4-d]pyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
A mixture of R-tert-butyl 4-(aminomethyl)-3,3-difluoropiperidine-1-carboxylate (440 mg, 1.60mmol), 6-chloro-1H-pyrazolo[3,4-d]pyrimidine (272 mg, 1.76 mmol) and DIPEA (0.84 mL, 4.80 mmol in i-PrOH (10 mL) was heated overnight at 85 C. The mixture was allowed to cool to room temperature and was concentrated under reduced pressure. The concentrate was purified by column chromatography over silica gel (hexane/ethyl acetate = 1/3) to afford the title compound as a yellow powder (510 mg, 86%). MS (ESI) calcd for C16H22F2N602: 368.2 ; found: 369.4 [M+H]. 1H NMR (400 MHz, CDCI3) 6 10.88 (brs, 1H), 8.78 (s, 1H), 7.92 (s, 1H), 5.77-5.67 (m, 1H), 4.50-4.00 (m, 2H), 3.90- 3.84 (m, 1H), 3.67-3.58 (m, 1H), 3.07-2.68 (m, 2H), 2.38-2.23 (m, 1H), 1.91-1.85 (m, 1H), 1.62-1.56 (m, 1H), 1.46 (s, 9H).
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 23002-51-9, 6-Chloro-1H-pyrazolo[3,4-d]pyrimidine.
