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 63558-65-6, name is 4-Chloro-5-iodopyrimidine. This compound has unique chemical properties. The synthetic route is as follows. COA of Formula: C4H2ClIN2
Step 1: (l-BenzyI-lH-pyrazol-3-yl)(4-chloropyrimidin-5-yl)methanol 4-Chloro-5-iodopyrimidine (300 mg, 1.25 mmol) was weighed into a 100 mL 2 necked RBF and the flask was purged with argon. This starting material was dissolved in THF (10 mL) and the solution was cooled to -78 C. To the solution was added n-Butyllithium (2.50 M in hexane; 1.0 mL, 2.5 mmol) at -78 C and then the mixture was stirred for 30 min. To this mixture was added dropwise a solution of 1 -benzyl- lH-pyrazole-3-carbaldehyde (211 mg, 1.1 mmol) in THF (4 mL), and the resulting mixture was stirred for 30 min. The reaction was quenched by addition of saturated NH4CI (50 mL) and extracted with EtOAc (50 mLx4). The combined organic layers were washed with brine, dried over Na2S04, filtered, and concentrated in vacuo. The residue was purified on silica gel to provide (1-benzyl- lH-pyrazol-3-yl)(4-chloropyrimidin-5-yl)methanol (304 mg, 85%) as a light yellow oil. LCMS (FA): m/z = 301.4 (M+H).
With the rapid development of chemical substances, we look forward to future research findings about 63558-65-6.
