Line structure of (CH3)2CH(CH2)3OC(CH3)3

Hello there! I was trying to write down the line strcuture of this molecule, (CH3)2CH(CH2)3OC(CH3)3, i know the first central C got H and 2 CH3 bonded to it and last C got three CH3 bonded to it but I'm confused bout that middle (CH2)3O , how do you add that to the structure ? May i ask for a line formula if that's ok ?
