there is an acidic hydrogen which will be preferentially abstracted in N-H so nucleophilic addition will not take place

Bonne annee is correct , grignard reagent contains one of the strongest bases in it , i.e R- , and hence it abstracts a proton , wichwill be an acid base reaction , i.e a very fast reaction .
