To a solution of 1-methyl-7-oxabicyclo[4.1.0]heptane, 30a, (1.0 g, 7.1 mmol) in water was added ammonium hydroxide (6.0 mL, 154.1 mmol). The mixture was heated to 50° C. for 48 hours. The mixture was diluted with water, extracted with EtOAc and then twice with 20% MeOH/CHCl3. The organic phases were dried (MgSO4), filtered and concentrated in vacuo to provide the desired product, 30b, as an amorphous white solid.
