2-Amino-1-benzyl-1H-pyrrole-3-carbonitrile

2-Amino-1-benzyl-1H-pyrrole-3-carbonitrile is an unblocked amine that is activated by the addition of a strong base such as pyridine. It has been shown to react with malononitrile and p-toluenesulfonic acid in the presence of a catalyst such as copper sulfate to form an acetal. The product can be deprotected by treatment with sodium azide or carbamates, followed by p-toluenesulfonic acid monohydrate. 2ABA is used in organic synthesis to form acetals, which are useful for protecting alcohols and other sensitive functional groups. 2ABA is also used to synthesize naphthols with p-toluenesulfonic acid monohydrate and dimethyl malonate.
