68.3% | In N,N-dimethyl-formamide; | Step 10: N-(3-((4S,6S)-2-amino-4-methyl-6-(trifluoromethyl)-5,6-dihydro-4H-1,3-oxazin-4-yl)-5-chloro-4-fluorophenyl)-5-cyanopicolinamide To a cooled (ice bath) solution of (4S,6S)-4-(5-amino-3-chloro-2-fluorophenyl)-4-methyl-6-(trifluoromethyl)-5,6-dihydro-4H-1,3-oxazin-2-amine (0.090 g, 0.276 mmol) and 5-cyano-2-pyridinecarboxylic acid (0.060 g, 0.405 mmol) in n,n-Dimethylformamide (1.5 mL) was added dropwise 2,4,6-tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide (0.352 mL, 0.553 mmol). After stirred for 1.5 h, reaction went to completion. The reaction mixture was quenched with saturated NaHCO3 and diluted with water. The resulted suspension was stirred for 30 min, and filtered. The filter caked was washed with water and purified by Shimadzu HPLC to afford the title compound (0.086 g, 0.189 mmol, 68.3% yield) as off-white solid. MS m/z=456.0 [M+H]+.
