how to consume web api by mvc in a synchronic way?

I need to consume a web api through an mvc project synchronously, however most of the examples are asynchronous,

I have the following code:

    [HttpGet]
    public async Task<ActionResult> Buscar(int? id)
    {
        //Get
        var vm = new VM_Prov();
        VM_Proveedores v = new VM_Proveedores();
        if (id.HasValue)
        {


            string apiUrl = "http://localhost:61698/Proveedor/Buscador?id=" + id;
            using (HttpClient client = new HttpClient())
            {
                client.BaseAddress = new Uri(apiUrl);
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));



                HttpResponseMessage response = await client.GetAsync(apiUrl);
                if (response.IsSuccessStatusCode)
                {
                    var data = await response.Content.ReadAsStringAsync();

                    v = Newtonsoft.Json.JsonConvert.DeserializeObject<VM_Proveedores>(data);
                    return View("Proveedores", v);
                }

            }
        }
        return View("Index", vm);
    }

Is there any way to do it in a synchronic way?
