You will need to create the *ngLet or *ngFor directive by following reference link:

This is the way I declare the variables into templates after creating the directives:

<ng-container  *ngFor="let item of users">
    <ng-container *ngLet="item.id as ref_var">
        <td  *ngIf="item.method == update.business_type">{{ref_var}}</td>
    </ng-container>
</ng-container>

This is also possible using *ngVar directive:

<ng-container  *ngFor="let item of users">
    <ng-container *ngVar="item.id as ref_var">
        <td  *ngIf="item.method == update.business_type">{{ref_var}}</td>
    </ng-container>
</ng-container>
