Isishwankathelo	I-3, i-4-dihydroxy-2 '-chloroacetophenone ngundoqo ophakathi kwi-synthesis ye-carbamot. ICarbazil ekwaziwa njengegazi, iadrenal pigment ammonia urea sodium salicylate, isetyenziswa ikakhulu ukonyuka kwecapillary permeability okubangelwa kukopha.
Sebenzisa	I-intermediate ye-haemostatic drug anluoxue, i-adrenomimetic drug gashaler, njl.
indlela yokuvelisa	yongeza i-catechol kunye ne-chloroacetic acid kwimbiza eyomileyo yokusabela, phakamisa ubushushu ukuya kwi-60 °c, kwaye uvuselele, i-85-90 degrees C insulation 0.5h. Ukupholisa ngaphantsi kwe-65 ℃, yongeza i-phosphorus oxychloride, uphendule ku-60-70 ℃ nge-4h, 70-80 ℃ nge-4h. Xa kunzima ukuvuselela i-reactants, yongeza amanzi, uphakamise ubushushu, kunye ne-hydrolyze kwi-90-100 ℃ nge-0.5h. Iikristale zapholiswa ukuya ngaphantsi kwe-10 ° C., kwaye zahluzwa. Umba oqinileyo wahlanjwa ngamanzi de ungathathi hlangothi ukufumana i-2-chloro-3 ',4′-dihydroxyacetophenone.
