Reaction Steps

The procedure of Example 1 was repeated except that 93 mg of 1α,3β-bis(methoxymethoxy)pregna-5,7-diene-20-carbaldehyde was used in lieu of 100 mg of 1α,3β-bis(methoxycarbonyloxy)pregna-5,7-diene-20-carbaldehyde to give 92 mg of 1α,3β-bis(methoxymethoxy)-20-methylpregna-5,7-dien-21-ol.
