Application of 53342-27-1, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.53342-27-1, name is 1-(2-Pyrimidinyl)ethanone, molecular formula is C6H6N2O, molecular weight is 122.1246, as common compound, the synthetic route is as follows.

Step 1-Synthesis of 2-(pyrimidin-2-yl)but-3-yn-2-ol A solution of 1-(pyrimidin-2-yl)ethan-1-one (2.5 g, 20.47 mmol) in tetrahydrofuran (60 mL) was added dropwise into a ethynylmagnesium bromide (0.5 M in tetrahydrofuran, 60 mL, 30 mmol) solution with stirring at room temperature under nitrogen atmosphere. The reaction mixture was stirred at room temperature for 1 hr and then quenched by the addition of saturated aqueous ammonium chloride (200 mL). The resulting solution was extracted with ethyl acetate (2*300 mL) and the combined organic layers were washed with brine (300 mL), dried over anhydrous sodium sulphate and concentrated in vacuo. The residue was purified on a silica gel column, elution with ethyl acetate/petroleum ether (0:1-1:1) afforded 2-(pyrimidin-2-yl)but-3-yn-2-ol (1.5 g, 50%) as yellow oil. 1H NMR (400 MHz, CDCl3) delta 8.82 (d, J=4.4 Hz, 2H), 7.33-7.29 (m, 1H), 5.1 (s, 1H), 2.56 (s, 1H), 1.93 (s, 3H); LC-MS: m/z=149 (M+H)+.

Statistics shows that 53342-27-1 is playing an increasingly important role. we look forward to future research findings about 1-(2-Pyrimidinyl)ethanone.

Step 2: 3-Dimethylamino-1-pyrimidin-2-ylpropenone On a very short distillation bridge, 11 g (90 mmol) of 2-acetylpyrimidine and 23 g (193 mmol) of DMF-DMA were stirred at 100 C. for 1 h, during which time some distillate passed over. The mixture was concentrated by evaporation and the residue was recrystallized from benzotrifluoride. Yield: 11.4 g (70% of theory) 1H-NMR (D6-DMSO): 3.1 (s, 6H), 6 (d, 1H), 7.5 (t, 1H), 7.7 (d, 1H), 8.9 (d, 2H)
