Error compiling jsx with Browserify ReactJS

Good morning,

I am totally new in the world of ReactJS. I am trying to make a trial app and I find the following. These are my files:

BtnLink.jsx:

    var BtnLink = new React.createClass({


    render : function(){
        return(
            <div>hola</div>
        )
    }
});
module.exports = BtnLink;

index.js

var Boton   = require('./components/BtnLink.jsx');

var app = {
    // Application Constructor
    initialize: function() {
        console.log("here with me");
        ReactDOM.render(<BtnLink>, document.getElementbyId('app'))
    },


    onDeviceReady: function() {
        this.receivedEvent('deviceready');
    },

    // Update DOM on a Received Event
    receivedEvent: function(id) {
        var parentElement = document.getElementById(id);
        var listeningElement = parentElement.querySelector('.listening');
        var receivedElement = parentElement.querySelector('.received');

        listeningElement.setAttribute('style', 'display:none;');
        receivedElement.setAttribute('style', 'display:block;');

        console.log('Received Event: ' + id);
    }
};

app.initialize();

This code is in a file "BtnLink.jsx", which I include, in my index.js file, according to the browserify documentation. But at the moment of running the command for the compilation:

browserify js/src/index.js -o js/dist/index.js

The console tells me that I have an error in the "hello" line in the BtnLink.jsx file. I really do not see any error, checking it with all the declaration examples. I think it's pretty similar. Does anyone know what I'm missing? Thank you very much.

Update: I updated the files, now apart, I'm trying to run it with babel with this command:

 babel --presets es2017 js/src/components --watch --out-dir js/dist/components

The result is the same, both with browserify and with babel returns to me that there is error in the hello :

SyntaxError: js/src/components/BtnLink.jsx: Unexpected token (6:3)
  4 |   render : function(){
  5 |           return(
> 6 |                   <div>hola</div>
    |                   ^
  7 |           );
  8 |   }
  9 | });
