Reference of 1558-17-4, 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. 1558-17-4, name is 4,6-Dimethylpyrimidine, molecular formula is C6H8N2, 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.
n-Butyllithium (2.5 M in hexanes; 5.00 mL, 12.5 mmol) was slowly added drop- wise to a -78 C solution of 4,6-dimethylpyrimidine (1.08 g, 9.99 mmol) in tetrahydrofuran (20 mL). After the reaction mixture had been stirred for 20 minutes at-78 C, solid carbon dioxide (dry ice, 5.0 g) was added, and the reaction mixture was warmed to room temperature (15 C) and stirred for 1 hour. Water (3.0 mL) was thenadded, and the resulting mixture was concentrated in vacuo to provide the product as a white solid. Yield: 1.53 g, 9.68 mmol, 97%. H NMR (400 MHz, D20) 8.78 (5, 1 H), 7.28 (5, 1 H), [3.60 (5) and 3.59 (br 5), total 2H], 2.43 (5, 3H).
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 1558-17-4, 4,6-Dimethylpyrimidine.
