Starting with cyclohexene and using any other reagents of your choice, show how you would prepare the following compound.

The transformation above can be performed with some reagent or combination of the reagents listed below. Give the necessary reagent$($s$)$ in the correct order, as a string of letters $($without spaces or punctuation, such as "EBF"$).$ If there is more than one corr solution, provide just one answer.

A

t$-$BuOH, NaOH

D

$HBr$

G

NaH

B

t$-$BuOK

E

$t-$BuBr

H

dilute $H_{2}S{O}_4$

C

$RC{O}_{3}H$

F

$Hg(OAC{)}_2,t-$BuOH; $2)NaB{H}_4$

I

t$-$BuOK; $2)H_3{O}^{+}$
