Versuchsvorschrift

tert-Butyl {methyl[6-(4-oxo-4H-1,3-benzothiazin-2-yl)-2-pyrimidinyl]amino}acetate (0.20 g, 0.52 mmol) was dissolved in trifluoroacetic acid (5 ml), and the mixture was stirred for 0.5 hr. Diisopropyl ether was added thereto. The obtained crystals were recrystallized from ethanol to give the titled compound (0.15 g, 87%) as pale yellow crystals.

Aufarbeitung

  1. customThe obtained crystals were recrystallized from ethanol
