Patent number: 10323010Abstract: The present invention pertains generally to the field of chemical synthesis, and more particularly to methods of chemical synthesis which include the step of preparing a substituted 10H-phenothiazine-3,7-diamine compound of Formula (1) by a step of selective alkylation by reductive amination, in which the corresponding unsubstituted diamine of Formula (4) is reacted with aldehyde/ketone, under reductive amination conditions. The present invention also relates to such methods which incorporate additional subsequent and/or preceding steps, for example, to prepare compounds of Formulae (2) and (3) from compounds of Formula (1), and to prepare compounds of Formula (4) from, for example, compounds of Formulae (5), (6), (7), (8), and (9). Compounds of Formula (1), Formula (2), and Formula (3) are useful, for example, in the treatment of diseases of protein aggregation, such as Alzheimer's disease.Type: GrantFiled: July 20, 2016Date of Patent: June 18, 2019Assignee: WISTA LABORATORIES LTD.Inventors: John Mervyn David Storey, Christopher Paul Larch, Steven John Kemp, Scott Clunas, Sarah Louise Nicoll, Helen Sarah Gibbard, Michael Simpson, James Peter Sinclair, Colin Marshall
