The synthetic route of 52311-50-9 has been constantly updated, and we look forward to future research findings.

Adding a certain compound to certain chemical reactions, such as: 52311-50-9, 2-Chloro-4-ethoxypyridine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, SDS of cas: 52311-50-9, blongs to pyridine-derivatives compound. SDS of cas: 52311-50-9

To a degassed mixture of 4-(4,4,5,5-tetramethyl-l,3,2-dioxaborolan-2-yl)benzamide ( 9.4g, 38 mmol) and 2-chloro-4-ethoxypyridine ( 5g, 31.7 mmol) in dioxane was added Brettphos-prePd (catalytic amount) and CS2CO3 (12.3 g, 37.8 mmol) under N2 atmosphere. The mixture was heated to 100 C and stirred for 3.5 hours. The reaction mixture was cooled to room temperature and filtered. The filtrate was concentrated, and the residue was purified on silic-gel (PE: EA = 100% ~ 30%) to give N-(4- ethoxypyridin-2-yl)-4-(4,4, 5, 5-tetramethyl- 1 ,3 ,2-dioxaborolan-2-yl)benzamide (8.8 g, yield 75%). 1HNMR (400MHz, CDC13): 5=8.74 (s, 1 H), 8.05-8.02(m, 1 H), 8.01 (s, 1 H), 7.94-7.89 (m, 4 H), 6.60-6.59 (m, 1 H), 4.20-4.14 (m, 2 H), 1.47-1.43 (m, 3 H), 1.36 (s, 12 H), MS (ESI): M/Z (M+l)=369.19.

The synthetic route of 52311-50-9 has been constantly updated, and we look forward to future research findings.
