Phenyl Acetaldehyde Dimethyl Acetal (Viridine) - Vigon

Webof aniline with benzyl dimethyl acetal at room temperature. The desired benzyl aniline was obtained at 73% yield (Table 1, entry 1). To improve the efficiency, a series of Lewis acids were screened. The results of this screening indicate that I 2 Et 3 SiH afforded the highest yield, 93% (Table 1, entries 1 12).
