So im trying to make 1-acetylcyclohexane from ethenylcyclohexane..and i have to make it in 4 stepsi got the first two steps but the last two is what i am unsure of..

1) Br2

2) 2 equiv NaNH2

3) ??

4) ??

i know the 1st two steps but im having trouble figuring out the last two steps here is the bank:

*excess NaNH2, then H2O

*bromocyclohexane

*NaBH4

*BH3/THF

*CH3Br

*SOCl2

*HBr

*H2

*H2, Lidlar catalyst

*CH3CH2Br

*H2O,H2SO4, HgSO4

*H2O2, NaOH, H2O

I originally thought it would be

1)Br2

2) 2 equiv NaNH2

3) H2O, H2So4, HgSO4

4) BH3/THF

....but that's wrong, can you please help me? Thank you!! :)
