Participants

Reaction Steps

According to the method described for 3-(2-difluoromethoxy-4-{1-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-propoxy}-phenyl)-4H-1,2,4-oxadiazol-5-one (except for the hydroxylamine addition step which was performed under microwave irradiation at 100° C. for 2 h), (+)-3-(2-difluoromethoxy-4-{(R)-1-[2-(4-trifluoromethyl-phenyl)-4-(4-trifluoromethyl-piperidin-1-ylmethyl)-thiazol-5-yl]-propoxy}-phenyl)-4H-1,2,4-oxadiazol-5-one was obtained from (R)-1-[2-(4-trifluoromethyl-phenyl)-4-(4-trifluoromethyl-piperidin-1-ylmethyl)-thiazol-5-yl]-propan-1-ol and 2-difluoromethoxy-4-fluoro-benzonitrile.
