Synthetic methods are required to make this structure on a multikilo scale and in high purity. The initial route to aminoquinazoline AZD8931 suffered from the formation of late-stage impurities. To avoid these impurities, a new high-yielding Dimrothrearrangement approach to the aminoquinazoline core of AZD8931 was developed. Assessment of route options on a gram scale demonstrated that the Dimroth rearrangement
