Paragraph 0324-0325, (2013/10/08)
The invention relates pyridine amide derivative of Formula (I) or a pharmaceutically acceptable salt thereof, wherein R1 and R2 are independently hydrogen, linear o branched (C1-C3)alkyl or joined together they form a cyclopropyl ring; R is independently selected from the group consisting of halogens and trifluoromethyl and p is 1, 2 or 3; A is C or N; E is a group of formula (B) or (C), wherein B is C(O)OH, C(O)O(C1-C3)alkyl, and C is selected from the group consisting of formula (I) m is 1,2 or 3, n is 0 or 1, W is —O—, —O(C1-C3 alkyl)-; —(C1-C3 alkyl)O—; —C(O)—; —C(═N—O(C1-C3 alkyl))-; —NH— or —NH(C1-C3alkyl)-; Ar is phenyl, optionally substituted with one or more substituents selected from the group consisting of halogen, trifluoromethyl, trifluoromethoxy, methyl, —NH(C1-C3alkyl)-; —N(C1-C3alkyl)(C1-C3alkyl)-, a from 5 to 7 membered heterocyclic ring containing one nitrogen atom which is covalently bonded to Ar and optionally containing one or two heteroatoms selected from N, O and S; and a 5- or 6-membered heteroaromatic ring containing 1 to 3 heteroatoms selected from S, O e N, such heteroaromatic ring being substituted with one or two substituents selected from the group consisting of (C1-C3)alkyl, (C3-C5)cycloalkyloxy, (C1-C3)alkylcarbonyl. The compounds of the invention could be used for manufacturing a medicament for the treatment of pathologies which require the use of an antagonist of the EP4 receptor, such as the treatment of acute and chronic pain, inflammatory pain, osteoarthritis, inflammation-associated disorder as arthritis, rheumatoid arthritis, cancer, endometriosis and migraine.

Process for preparing 3-phenoxy-1-azetidines and carboxamide derivatives
-
, (2008/06/13)
An improved process is disclosed for preparing 3-phenoxyazetidines which utilizes a phase transfer catalyst to add the phenoxy group to azetidine blocked in the 1-position by a diphenylmethane group and utilizes a stabilizing tertiary amine base to prevent dimerization during hydrogenolysis to remove the blocking group. The crude product containing diphenylmethane may be used without purification to prepare 3-phenoxy-1-azetidinecarboxamides.
