发明名称 IMPROVED PROCESS FOR THE PREPARATION OF 2-TRIFLUOROMETHYL-5-(1-SUBSTITUTED)ALKYLPYRIDINES
摘要 2-Trifluoromethyl-5-(1-substituted)alkylpyridines are produced efficiently and in high yield from an 4-alkoxy-1,1,1-trifluorobut-3-en-2-one by a condensation and a cyclization reaction. Both reactions are performed in the same nonpolar solvent without isolation and purification of intermediates.
