Method as described for intermediate 5 using tert-butyl (5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thiazol-2-yl)carbamate and (S)-4-(2-chloro-7-methyl-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidin-4-yl)-3-methylmorpholine (intermediate 13) as starting materials. The tert-butyl carboxylate group was removed under the reaction conditions. The mixture was concentrated in vacuo and purified by flash SCX2 chromatography affording (S)-5-(7-methyl-4-(3-methylmorpholino)-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidin-2-yl)thiazol-2-amine.
