Breastfeed to bottle

I have been trying to get LO to try bottle feeding which he refuses all the time as he was breastfed for a very long period of time. He reject bottles before even trying... is there any way i can get him to wean off breastmilk? Usually in the day he can eat solids and drink some other stuff and fall asleep himself but when night time comes he have to latch on to sleep and I really want to stop breastfeeding ASAP. TIA!!!
