Property 'xxx' does not exist on type 'Observable

After upgrading Angular, original code below complaints

ngOnInit() {    ...    Observable.fromEvent(this.filter.nativeElement, "keyup")        .debounceTime(150)        .distinctUntilChanged()        .subscribe(...  

Based on this thread, I changed Observable.fromEvent to fromEvent. Now goes down to debounceTime, and distinctUntileChanged() will be next.

How to convert the original one?
