In 10 ml of methanol was dissolved 100 mg of 1α-acetoxy-3β-(methoxymethyl)oxypregna-5,7-diene-20-carbaldehyde, followed by addition of 50 mg of sodium methoxide. The mixture was stirred in an atmosphere of argon gas for 2 hours. The reaction mixture was then worked up in the same manner as Example 164 to give 80 mg of 1α-hydroxy-3β-(methoxymethyl)oxypregna-5,7-diene-20-carbaldehyde showing the following physical properties.
