Couldn't "ni" particle be used in this example?


I'm a total newbie learning japanese as you will see, so please be patient
with me. I have this sentence from my textbook:

> Shiken no toki jisho o minai de kudasai!

Because it was a new lesson, I didn't know what were the meanings for `shiken`
or `toki`, so I've just assumed that `toki` is an adjective for `jisho` and
after I've looked up the words in the vocabulary section, it suddenly became
really strange for me to think about how am I going to translate it.

So, my question is: Couldn't `ni` particle be used there between `toki` and
`jisho`:

> Shiken no toki **ni** jisho o minai de kudasai!

to mark the time in which the action takes place? I know the sentence is
obvious for someone who does know japanese, but I'm only asking this for
grammar purposes.

Thank you for your patience!




Yes, you can use **ni** there.

> Shiken no toki **ni** jisho o minai de kudasai!

This sentence is grammatically correct and actually used. A web site
<https://oshiete.goo.ne.jp/qa/98363.html> explains the reason:

>
> 2)「時間の名詞」が複合の形をとる場合、例えば、「おととい」という時間を表わす名詞にさらに「朝」という時間を表わす名詞がついて「おとといの朝」などという形になる場合はやや複雑で、「あしたの昼、テニスをします」と助詞を伴わずにも使われますし，「あしたの昼に、テニスをします」と助詞を伴っても使われます。この二つの文の場合ですが，意味的には実は違いがありません。「に」を伴うことによって「強調」を表わしていると思われる傾向にあるようですが，この場合の「に」は「格助詞」として「より顕著な副詞表現に属することを表わしている」に過ぎません。

I understand the example

> Shiken no toki **ni**

is

> 「時間の名詞」が複合の形をとる場合

.
