N-(Pyridin-2-ylmethyl)pyridin-2-amine [PDF]
The title compound, C(11)H(11)N(3), crystallizes with two mol-ecules (A and B) in the asymmetric unit. The geometries of both mol-ecules are very similar, with the exception of the torsion angles of the inter-ring chains; the values for C-N-C-C are 67.4 (5) and -69.3 (5)° for mol-ecules A and B, respectively.

Synthesis of tetrahydrofuro[3,2-c]pyridines via Pictet–Spengler reaction
A semi-one-pot method for the synthesis of 4-substituted tetrahydrofuro[3,2-c]pyridines by the Pictet–Spengler reaction was developed. The method is based on the condensation of easily accessibly 2-(5-methylfuran-2-yl)ethanamine with commercially ...
