Single word meaning 'to put to sleep' (best translation of 'endormir' from French)

I'm looking for a very particular word meaning 'to put to sleep'.

There is a verb in French, 'endormir', which is the meaning I'm trying to capture. It functions similarly to 'invigorate' in that it means 'to give vigor to', endormir is a bit like 'to give sleep to' or perhaps 'to render sleeping'.

The closest I found was 'sedate' but that implies a use of sedatives, I think.

I am nearly certain that there is a single word in English that captures this. Something like if 'soporific' was a verb.

Example sentence in French: Ses devoirs l'ont endormi.

Translation: His homework (put him to sleep). (Looking to replace 'put him to sleep' with a single word, something like 'his homework sedated him'.)

Just a single word meaning 'to render sleeping' or 'to put to sleep' is best.

Thanks in advance for your help (:

There’s “lull”. The definition at thefreedictionary.com says “1. To cause to sleep or rest; soothe or calm.” But it would normally be used as “it lulled me to sleep”, not just “it lulled me”.
