Any difference between these three sentences?


  * 彼は私達に騒がないように頼んだ。
  * 彼は私達に騒がないと頼んだ。
  * 彼は私達に騒がない頼んだ。

Is there any difference between those?




> 彼は私たちに騒がないように頼んだ。◎ He told us not to be noisy.

No issues with this sentence.

> 彼は私たちに騒がないと頼んだ。✘

Without the ように, we would assume that the と is functioning as a quotative
particle, which means that 「騒がない」would be what is being quoted. 「騒がないで」would
be an appropriate fix.

[code]

    彼は私たちに「騒がないで」と頼んだ。◎ He told us 'Don't be noisy'.
    
[/code]

> 彼は私たちに騒がない頼んだ。✘

Using the simple negative form 「ない」 here would serve an adjectival function.
Therefore, the verb should be changed to a noun (頼み）.

[code]

    私たちは彼に騒がないという頼みを受けたんだ。【～微妙～】　
    'We received a request from him to not be noisy.
    
[/code]

Probably best to avoid this last one as, despite being better grammatically,
it is an unusual way to form the expression.
