Begin by numbering the phenyl ring so that the ring carbon bearing the amide is C1. Attached to C1 is the amide carbonyl (-C(=O)-). The nitrogen of this amide carries two substituents: (1) an isopropyl group (-C(CH3)2) and (2) an ethyl chain attached to a nitrile group -CH2-CH2-CN, where -CN denotes a nitrile group in which the carbon is triple-bonded to a nitrogen.
Also, at C4 of the phenyl ring is an -O-CH2- linkage leading to a tetrahydrofuran ring. Specifically, a saturated five-membered ring containing one oxygen and four additional carbons with the oxygen adjacent to the point of attachment of the linkage.
