Procedure

To a stirring solution of 3-[2-(methoxy)ethenyl]tetrahydro-2H-pyran (2.22 gm) in THF (15 ml) was added 2N hydrochloric acid (15 ml). After 1 h the mixture was diluted with water and extracted three times with ether. The combined extracts were washed with brine, dried (Na2SO4) and evaporated to give the title product as a pale yellow oil, yield 1.79 g.
