The present invention provides a novel compound having FGFR inhibitory activity or a pharmaceutically acceptable salt thereof, and a pharmaceutical composition containing the same. Specifically, the present invention provides a compound represented by the following formula (I) or a pharmaceutically acceptable salt thereof:
wherein n represents 0 to 2; A represents an arylene group or a heteroarylene group; G represents a single bond, an oxygen atom or —CH
2
—; E represents a nitrogen-containing non-aromatic heterocycle; R
1
represents an alkoxy group or the like; R
2
represents a hydrogen atom or the like; and R
3
represents a hydrogen atom, an alkyl group, an alkoxy group or the like, with the proviso that when E represents an azetidine ring and R
2
or R
3
is present on a nitrogen atom on the azetidine ring, the R
2
or R
3
does not represent a hydrogen atom.

photoacid system containing catalytic protonated merocyanine (MEH). Under visible-light irradiation, MEH yields a metastable spiro structure and liberated protons, which facilitates the formation of carbocations from benzyl alcohols, thus delivering diverse molecules in the presence of various nucleophiles. Mainly, a variety of indanes could be easily obtained from benzyl alcohols and olefins, and water
