Disclosed is a novel process for production of lasofoxifene, nafoxidine or an analogue thereof, which comprises reduced number of reaction steps, has a high efficiency, and is practically advantageous. For the production of lasofoxifene or an analogue thereof, a compound represented by the formula (4) is used as an intermediate. The compound represented by the formula (4) can be produced using compounds represented by the formulae (1) to (3) as starting compounds by performing the coupling of the three components in one step.
