A compound represented by formula (I) or a pharmaceutically acceptable salt thereof has an effect of inhibiting CRTH2 and, therefore, is useful as a preventive or a remedy for allergic diseases such as asthma, atopic dermatitis and allergic rhinitis.

classical Blaise reaction. The products were further transformed to useful small organic molecules (SOMs). Studies on the reactivity of nitriles via intra and inter-molecular competition experiments showed that anchimericassistance from the neighbouring and strategically located ester is crucial for higher reactivity of the nitrile in the 3-cyanopropionates towards the Blaise reaction.
