Axios Request Interceptor wait until ajax call finishes

I have an request interceptor for axios calls. It checks my jwt token and call for refresh if necessary.

axios.interceptors.request.use((config) =>{

    const state = store.getState(); // get renewed state
    const time = Math.floor( new Date().getTime() / 1000 );

    if( 
        ! state.app.jwtRefreshOnRequest 
        && time >= state.jwt.expires - 120
        && state.jwt.refresh_before > time
    ){ // expiring in 2 min. refresh    

        //dispatch({type: 'JWT_REFRESH_REQUEST'});
        axios.get( API_BASE_URL + '/auth/refresh')
            .then(function(response){
                // dispatch({type: 'JWT_REFRESH_SUCCESS', payload: response.data});
                axios(config).then(resolve, reject);
            })
            .catch(function(err){               
                reject(err);
        });

    }       

    return config;
}); 

This code calls the refresh correctly and saves the new token but the original call doesn't holds until the interceptor request is done, so the expired token is used.

So, I guess I need to make synchronous call from interceptor.
