A low-temperature continuous-flow preparation method of bedaquiline includes the following steps. (a) A first feed liquid and a second feed liquid are subjected to a first continuous flow reaction for 30-600 seconds to obtain a first reaction mixture. (b) The first reaction mixture and a third feed liquid are subjected to a second continuous flow reaction for 30-600 seconds to obtain a second reaction mixture. (c) The second reaction mixture was quenched to afford bedaquiline.
