Reaction Steps
The procedure of Example 36 was repeated except that 2.5 mg (0.005 mmole) of 20-(5,5-dimethyl-1,3-dioxan-2-yl)-1α,2α-epoxy-7α-(N-methylcarbamoyloxy)pregn-5-en-3β-ol was used in lieu of 2.2 mg of 20-(5,5-dimethyl-1,3-dioxan-2-yl)-1α,2α-epoxypregn-5-ene-3β,7α-diol to give 1.3 mg of 1α,2α-epoxy-3β-hydroxy-7α-(N-methylcarbamoyloxy)pregn-5-ene-20-carbaldehyde (yield: 62%).
