实验过程
The procedure of Example 11 was repeated except that 65 mg of methyl 1α,3β-bis(methoxymethoxy)pregna-5,7-diene-20-carboxylate was used in lieu of 70 mg of methyl 1α,3β-bis(methoxycarbonyloxy)pregna-5,7-diene-20 carboxylate to give 47 mg of 1α,3β-bis(methoxymethoxy)-20methylpregna-5,7-diene-21-ol, whose 1H NMR spectrum was identical with that obtained in Example 10.
