Versuchsvorschrift

1-(2,4-dichloro-pyrimidin-5-yl)-ethanone (10 g, 0.052 mol), sodium hydrogen carbonate (19.35 g, 0.058 mol) and isopropylamine (5 mL, 0.058 mol) are taken up in 35 mL THF and 200 mL cyclohexane and stirred for 2 h at 20° C. The reaction solution is filtered through silica gel, the solvent is eliminated in vacuo and 1-(2-chloro-4-isopropylaminopyrimidin-5-yl)-ethanone (HPLC-MS: tRet.=1.73 min, MS(M+H)+=214/216; method FECB3) is obtained.

Aufarbeitung

  1. filtrationThe reaction solution is filtered through silica gel
