Predictions:

Position	Integration	Splitting	Chemical Shift
1	2	Three nearest neighbours that are equivalent – quartet	Single bond to oxygen – deshielded
2	3	Two nearest neighbours that are equivalent – triplet	Saturated alkyl group far from ester group – shielded
2′	3	No nearest neighbours – singlet	Adjacent to the carbon of a carbonyl – slightly deshielded
