SYNTHETIC INTERMEDIATE OF OXAZOLE COMPOUND AND METHOD FOR PRODUCING THE SAME

摘要

AN OBJECT OF THE PRESENT INVENTION IS TO PROVIDE A METHOD FOR PRODUCING AN OXAZOLE COMPOUND IN A HIGH YIELD. THE OBJECT CAN BE ACHIEVED BY A COMPOUND REPRESENTED BY FORMULA (11): WHEREIN R¹ IS A HYDROGEN ATOM OR C1-6-ALKYL GROUP; R² IS A 1-PIPERIDYL GROUP SUBSTITUTED AT THE 4-POSITION WITH A SUBSTITUENT SELECTED FROM (A1A) A PHENOXY GROUP SUBSTITUTED ON THE PHENYL MOIETY WITH ONE OR MORE HALOGEN-SUBSTITUTED C1-6-ALKOXY GROUPS, (A1B) A PHENOXY-SUBSTITUTED C1-6-ALKYL GROUP SUBSTITUTED ON THE PHENYL MOIETY WITH ONE OR MORE HALOGEN-SUBSTITUTED C1-6-ALKYL GROUPS, (A1C) A PHENYL-SUBSTITUTED C1-6-ALKOXY C1-6-ALKYL GROUP SUBSTITUTED ON THE PHENYL MOIETY WITH HALOGEN, (A1D) A PHENYL-SUBSTITUTED C1-6-ALKYL GROUP SUBSTITUTED ON THE PHENYL MOIETY WITH ONE OR MORE HALOGEN-SUBSTITUTED C1-6-ALKOXY GROUPS, (A1E) AN AMINO GROUP SUBSTITUTED WITH A PHENYL GROUP SUBSTITUTED WITH ONE OR MORE HALOGEN-SUBSTITUTED C1-6-ALKOXY GROUPS, AND A C1-6-ALKYL GROUP, AND (A1F) A PHENYL-SUBSTITUTED C1-6-ALKOXY GROUP SUBSTITUTED ON THE PHENYL MOIETY WITH ONE OR MORE HALOGEN-SUBSTITUTED C1-6-ALKOXY GROUPS; N IS AN INTEGER FROM 1 TO 6; AND X3 IS AN ORGANIC SULFONYLOXY GROUP.
