Claim:
A compound of formula (I) wherein A represents X represents O, or S; R 2 represents (C 1-4 )alkyl; D represents aryl, which is unsubstituted, mono-, di, or tri-substituted wherein the substituents are independently selected from the group consisting of (C 1-4 )alkyl, (C 1-4 )alkoxy, trifluoromethyl, and halogen; R 1 represents aryl, wherein the aryl group is selected from the group consisting of a phenyl-, a naphthyl-, a 2,3-dihydro-benzofuranyl-, a benzo[1,3]dioxolyl-, a 2,3-dihydro-benzo[1,4]dioxinyl-, a 4H-benzo[1,3]dioxinyl, a 2H-chromenyl-, a chromanyl-, a 3,4-dihydro-2H-benzo[1,4]oxazinyl-, and a 3-biphenyl group, wherein said groups are unsubstituted, mono-, di, or tri-substituted wherein the substituents are independently selected from the group consisting of (C 1-4 )alkyl, (C 1-4 )alkoxy, trifluoromethyl, halogen and nitro; or R 1 represents heteroaryl, which is unsubstituted, mono-, di, or tri-substituted, wherein the substituents are independently selected from the group consisting of (C 1-4 )alkyl, (C 1-4 )alkoxy, halogen, hydroxy-(C 1-4 )alkyl, and trifluoromethyl; in a free or a pharmaceutically acceptable salt form.
