Problem with use of ambient declaration file

I have two scenarios in which I want to use a backbone.d.ts ambient declaration. The first is a definition file for intellisense of a plain js file I do not wish to convert to typescript. The second is a module that extends Backbone.Model and will be used by my view.

My definition file:

/// <reference path="../dep/backbone/backbone.ref.d.ts" />

interface IApi {
    version: number;
    Events: Backbone.Events;

declare var api: IApi;

My module:

import Backbone = module("../../../dep/backbone/backbone");

export class Codebook extends Backbone.Model {

    defaults() {
        return {
            id: -1,
            title: -1

    initialize() {
        // do nothing


The problem is that the definition file requires that the backbone.d.ts file include a module declaration: declare module Backbone. The module requires that this line be omitted in order to use the Backbone import and extend from it.
