The present invention relates to ethynyl derivatives of formula (I) wherein Y is N or CH R1 is fluoro or chloro R2 is hydrogen or methyl or to a pharmaceutically acceptable acid addition salt, to a racemic mixture, or to its corresponding enantiomer and/or optical isomer and/or stereoisomer thereof. It has now surprisingly been found that the compounds of general formula I are metabotropic glutamate receptor antagonists (negative allosteric modulators) for use in the treatment of anxiety and pain, depression, Fragile-X syndrom, autism spectrum disorders, Parkinson's disease, and gastroesophageal reflux disease (GERD).
