Application of 33252-28-7, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 33252-28-7, name is 6-Chloronicotinonitrile, molecular formula is C6H3ClN2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Step 1: 6-Isopropoxynicotinonitrile (48). To a stirring suspension of Potassium tert-butoxide (6.0 g, 54.12 mmol) in THF (200 mL) at 0 C. was added isopropanol (4.17 mL, 54.13 mmol) and the reaction mixture was stirred for 5 min. Compound 47 (5.0 g, 36.08 mmol) was added at 0 C. and the reaction mixture was stirred for 2 h at room temperature. The reaction mixture was concentrated in vacuo, the resulting residue was dissolved/suspended in water and extracted with EtOAc. The combined organic layers were washed with sat. NaCl, dried and concentrated to afford 48 (5.6 g) which was used as such for the next step.
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 33252-28-7, 6-Chloronicotinonitrile.
