  The invention provides a pyrazolo[1,5-a]pyrimidine derivative of the following formula (1): wherein R¹ is hydrogen, lower alkyl which may have thienyl, lower alkoxy, lower alkylthio, oxo or hydroxyl as a substituent, cycloalkyl, thienyl, furyl, lower alkenyl, or phenyl which may have 1 to 3 substituents selected from the group consisting of lower alkyl, lower alkoxy, phenylthio and halogen; R² is naphthyl, cycloalkyl, furyl, thienyl, optionally halogen-substituted pyridyl, optionally halogen-substituted phenoxy, or phenyl which may have 1 to 3 substituents selected from the group consisting of lower alkyl, lower alkoxy, halogen, nitro, halogen-substituted lower alkyl, halogen-substituted lower alkoxy, lower alkoxycarbonyl, hydroxyl, phenyl(lower)alkoxy, amino, cyano, lower alkanoyloxy, phenyl and di(lower)alkoxyphosphoryl(lower)alkyl; R³ is hydrogen, phenyl or lower alkyl; R⁴ is hydrogen, lower alkyl, lower alkoxycarbonyl, phenyl(lower)alkyl, optionally phenylthio-substituted phenyl, or halogen; R⁵ is hydrogen or lower alkyl; R⁶ is hydrogen, lower alkyl, phenyl(lower)alkyl, or benzoyl having 1 to 3 substituents selected from the group consisting of lower alkoxy, halogen-substituted lower alkyl and halogen; R¹ and R⁵ may conjointly form lower alkylene; Q is carbonyl or sulfonyl; A is a single bond, lower alkylene or lower alkenylene; and n is 0 or 1. This derivative is useful as a potent analgesic.
