title: 4-(3,4-Dihydro-β-carbolin-1-yl)pyrimidin-2-amine.
abstract: The mol-ecule of accanthomine A, C(15)H(13)N(5), is approximately planar, with the indolyl fused-ring and the pyrimidyl ring being twisted by 31.7 (1)° The amino group of the five-membered ring is an intramolecular hydrogen-bond donor to a nitro-gen acceptor of the pyrimide ring. The amino group of the pyrimide ring is a hydrogen-bond donor to the N atoms of adjacent mol-ecules. These hydrogen-bonding inter-actions give rise to a layered network with a 4.8(2) topology.
