0,344g N-(4-Bromo-5-iodo-2-thiazolyl)-2,2-dimethylpropanamid (0,88mmol, 1,00eq) wurden in einen 50ml Dreihalskolben eingewogen und in 5ml Dioxan gelöst.

According to my dictionary this means to "lull or rock to sleep", however, I suspect that this is not the correct meaning for this word in the context of the above sentence. Could it perhaps mean "to weigh out into something"
e.g.
"0,344g N-(4-Bromo-5-iodo-2-thiazolyl)-2,2-dimethylpropanamid (0,88mmol, 1,00eq)was then weighed out into a three-necked flask and dissolved in 5ml dioxane."


N.B. If the "to lull or rock to sleep" is also a valid translation of this word (albeit in a different context) then that too ought to be added to LEO.
