How do I get a median filtered image? I want to convert the first image like the second image using median filter.

If you have the Image Processing Toolbox, you can use medfilt2.

When I use medfilt2 code, I am getting the image exactly like my first image.

Have you tried increasing the size of the kernel. The default is 3x3. Your desired output image is extremely blurred indicative of a large kernel.
Try
medfilt2(img, [10 10]); %kernel size of 10
Note that even with the default, the output of medfilt2 is never exactly the same as the input (unless your image is just uniform)
