Procedure
Ethyl 4-benzyloxymethyl-2,4-dimethyl-1,3-dioxolan-2-carboxylate (5.0 grams) and concentrated aqueous ammonia solution (50 milliliters, 0.880 S.G.) were stirred together at room temperature for 3 days. The white solid formed was filtered off, washed with water and recrystallised from cyclohexane to give the desired product as an isomer mixture melting point 72°-92° C.
