Ammonia → N-formyl-1-(3-benzyloxyphenyl)ethylamine

Participants

Reaction Steps

In the same manner as in Example 5 except that 405 q of ammonium formate was placed in the reaction vessel, 569 g of 76% formic acid was placed in the pot of the ammonia absorbing tower, 3'-benzyloxyacetophenone and the pot solution of the ammonia absorbing tower were added to the vessel at 2.54 g/min. and 3-6 g/min. respectively over 3 hours in place of 2',4'-dichloroacetophenone at 0.86 g/min. and the pot solution of the ammonia absorbing tower at 0.48 g/min, and the stirring time after addition was 10 hours in place of 7 hours, the reaction and post treatment were carried out to obtain 497 g of crude N-formyl-1-(3-benzyloxyphenyl)ethylamine (the purity: 97.8%) in place of 2',4'-dichloroacetophenone at 0.86 g/min. and the pot solution of the ammonia absorbing tower at 0.48 g/min.
