Adding a certain compound to certain chemical reactions, such as: 1146629-77-7, name is (4-(1H-Pyrazol-4-yl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)methyl pivalate, belongs to pyrazoles-derivatives compound, 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 1146629-77-7, Formula: C15H17N5O2
To a solution (15 mL) of 37 (514 mg, 1.72 mmol, preparation described in Lin, Q. et al. Org. Lett., 2009, 11, 1999-2002) in acetonitrile was added 44 (537 mg, 4.29 mmol) , Then DBU (540 muL, 3.61 mmol) was added. The reaction was stirred at room temperature for 15 h and then concentrated under reduced pressure. The resulting crude mixture was diluted with water and extracted with ethyl acetate (3 x 50 mL). The combined organic layers were washed with 1 N HCl, dried (Na 2 SO 4), filtered and concentrated under reduced pressure. Purification by normal phase column chromatography (SiO 2, 0 to 60% ethyl acetate / hexane) gave (+/-) 45 as a white foam (368 mg, 50%)
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, (4-(1H-Pyrazol-4-yl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)methyl pivalate, other downstream synthetic routes, hurry up and to see.
