YieldReaction ConditionsOperation in experiment
94% With hydrogen; triethylamine In methanol at 40℃; for 2h; I.1.3 1.1.3 (2-Methyl-pyrimidin-4-yl)-methylamine; An autoclave was charged with 2-methyl-pyrimidine-4-carbaldehyde oxime (13 g) from 1.1.2, 150 ml of methanol and 70 ml of triethylamine. The autoclave was purged with nitrogen. To this mixture was added 3 g of a 10% palladium-on-carbon catalyst. The autoclave was sealed and purged twice with hydrogen gas. The hydrogenation was run for 2 h. In doing this, the reaction mixture was warmed up to 400C in the meantime. The precipitate was filtered off, washed with methanol to yield the title compound as light red solid (1 1 g, 94%).

General Synthetic Procedures for the Synthesis of (3S,11aR)-N-(heterocyclylmethyl)-6-hydroxy-3-methyl-5,7-dioxo-2,3,5,7,11,11ahexahydro[1,3]oxazolo[3,2-a]pyrido[1,2-d]pyrazine-8-carboxamides (1{2e4,7,10,13e21,23,25,28e34,36,38,44,46,47,50,53e55}) General procedure: To a solution of 0.5 mmol of (3S,11aR)-6-(benzyloxy)-8-bromo-3-methyl-2,3,11,11a-tetrahydro[1,3]oxazolo[3,2-a]pyrido[1,2-d]pyrazine-5,7-dione (6) [13] in 2 ml of DMSO was added 0.75 mmolof heterocyclylmethylamine (7) or its hydrochloride, 0.131 ml(0.75 mmol plus an additional 0.75 mmol for each hydrochloride) ofdiisopropylethylamine and 29 mg (0.025 mmol) of Pd(PPh)4. Thereaction mass was stirred for 14 h at 90 C in a CO atmosphere.Upon completion of the reaction (control LC-MS), the reaction masswas is evaporated in vacuo. The residue was dissolved in DCM,washed with water, dried over sodium sulfate, evaporated on arotary evaporator and subjected to column chromatography onsilica gel. Furthermore, a) 0.35 mmol of 8was dissolved in a mixtureof 18 ml of THF and 2 ml of methanol, and 0.04 g of 10% Pd/C wasadded and the mixture stirred in a hydrogen atmosphere for 8 h.The reaction mixturewas passed through Celite and the filtratewasevaporated. The residue was treated with ether, the precipitatewasfiltered and dried under vacuum to receive the corresponding target product 1. b) Compound 8 (0.35 mmol) was dissolved in 2mlof trifluoroacetic acid and stirred for 2 h at room temperature. Thesolution was evaporated in vacuo, and the residue was dissolved inchloroform, washed with saturated NaHCO3 solution, dried overNa2SO4 and evaporated in vacuo. The residue was treated withether, the precipitate was filtered and dried under vacuum toreceive the corresponding target product 1. c) Compound 8(0.35 mmol) was dissolved in 1.5 ml of N,N-dimethylacetamide,0.148 g (3.5 mmol) of LiCl was added and the solution stirred for 3 hat 80 C. Upon completion of the reaction (control LC-MS), the reactionmass was evaporated in vacuo. The product was isolated byHPLC to receive the corresponding target product 1.
