Error message [SOLVED]

Hello today I bought a starter kit for arduino UNO and I'm trying to check if a button is pressed and if it is the turn on a LED that is on the other side of the breadboard ,but I get a "expected constructor, destructor, or type conversion before '}' token" here is my code:

int pushButton = 2;
int LED = 4;

void setup() {
  Serial.begin(9600);
  pinMode(pushButton, INPUT);
  pinMode(LED, OUTPUT);
}

void loop() {
  int buttonState = digitalRead(pushButton);

  Serial.println(buttonState);

  if(buttonState = 1){
    digitalWrite(LED, HIGH);
  }else{
    digitalWrite(LED, LOW);
  }
  }
  delay(100);
}

What was the problem and how did you solve it ?
