Reaction Steps

Concentrated aqueous ammonia (50 mL) was added to methyl tetrahydro-2H-pyran-4-carboxylate (50 g, 347 mmol) and the reaction mixture was stirred for 43.5 hours at room temperature. The reaction mixture was then cooled in an ice water bath, after which the precipitate was filtered out and dried under reduced pressure at 40° C. to afford 33.4 g of the title compound (74.6% yield).
