  Multigram preparation of 2-alkylpyrimidines in the vapor phase from carboxylic acids and 1,3-diaminopropane over a dual catalyst system

  摘要：

  2-Alkylpyrimidines 2 were obtained from cofeeding a carboxylic acid such as pivalic acid (3a) or propionic acid (3b) and 1,3-diaminopropane (4) over first an alumina catalyst at 250-290-degrees-C and second a palladium dehydrogenation catalyst at 300-340-degrees-C to give 2 directly in 56-68% overall yields. On the alumina bed, initial amidation of organic acid occurs to give the monoacyltrimethylenediamine 5, followed by ring closure to the tetrahydropyrimidine intermediate 6. An equilibrium between 5, 6, and water is established on the alumina bed, with an apparent equilibrium constant of 53 +/- 7 mol/Kg at 290-degrees-C. The high temperature of the alumina bed shifts the equilibrium in favor of 6, which is directly dehydrogenated to 2 over the palladium catalyst. The method avoids the need to isolate and purify solid intermediates. The presence of low levels of sulfur acts as a strong palladium catalyst deactivator. Gradual decline of palladium catalyst activity was observed due to carbon buildup. No decline in alumina catalyst activity was observed. The continuous process allows for the preparation of multigram quantities of 2 with a laboratory-scale reactor.

  3-Aminopropylpivalamide is prepared by contacting pivalic acid with 1,3-diaminopropane at temperatures above the boiling point of 1,3-diaminopropane and the latter is distilled off. The residue may be refluxed to provide 2-t-butyltetrahydro-pyrimidine. In a further step 2-alkylpyrimidines are obtained by dehydrogenation of the tetrahydro-pyrimidines over a supported noble metal catalyst under conditions which do not generate water and in which no water is added.

  在高于 1,3- 二氨基丙烷沸点的温度下，将新戊酸与 1,3- 二氨基丙烷接触，然后蒸馏掉后者，即可制备 3-氨基丙基新戊酰胺。残留物经回流可得到 2-t-丁基四氢嘧啶。下一步，在不产生水和不加水的条件下，在支撑贵金属催化剂上对四氢嘧啶进行脱氢反应，得到 2-烷基嘧啶。

  The useful life of the palladium dehydrogenation catalyst used in the preparation of 2-alkylpyrimidines from 1,3-diaminopropane and an appropriate alkanecarboxylic acid in a continuous vapor phase process is substantially increased by employing a stoichiometric excess of the carboxylic acid and by using catalyst pellets of less than 3-4 mm diameters. Additionally, the dehydrogenation catalyst can be regenerated in situ by controlled air oxidation below 350°C.

  在以 1,3-二氨基丙烷和适当的烷基羧酸为原料制备 2-烷基嘧啶的连续气相工艺中，通过使用按化学计量过量的羧酸和使用直径小于 3-4 毫米的催化剂颗粒，钯脱氢催化剂的使用寿命大大延长。此外，脱氢催化剂可通过低于 350°C 的受控空气氧化就地再生。
