79% With N,N-dimethyl-formamide; trichlorophosphate; In acetonitrile; at 70℃; for 16.0h; To a solution of the product from the previous step (100 mg, 0.414 mmol) in acetonitrile (1.7 mL) was added POCb (68 mu, 0.72 mmol) and DMF (13 mu, 0.17 mmol) and the resulting mixture was stirred at 70 C for 4 h. Additional POCI3 (113 mu, 1.2 mmol) was added and the mixture was stirred at 70 C for 12 h. The mixture was concentrated and the residue was taken up in CH2CI2 (10 mL) and partitioned with aqueous sat. NaHC03 (2 mL). The aqueous layer was extracted with CH2CI2 (3 x 3 mL) and the combined organic layers were washed with NaHC03 (1 mL), brine (1 mL), dried over Na2S04, filtered and concentrated. The residue was purified via silica gel chromatography (0 - 10 % MeOH in CH2CI2) to afford the title compound (85 mg, 79 % yield) as a brown liquid.MS (ES+) C14H14CIN3 requires: 259, found: 260 [M+H]+.
57.8% 6-Benzyl-4-chloro-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine A mixture of <strong>[109229-22-3]6-benzyl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-4(3H)-one</strong> (5.0 g, 0.02 mol), phosphoryl chloride (3.30 mL, 0.035 mol) and acetonitrile (80 mL) and DMF (catalytic amount) was heated to at 70 C. for 1 hour. The mixture was reduced in vacuo and the remaining black residue was taken up in dichloromethane (250 ml) and poured over ice. The mixture was carefully neutralized with the addition of solid sodium bicarbonate. The layers were separated and the organic dried over sodium sulfate and reduced in vacuo. The mixture was chromatographed using an ethyl acetate:hexanes (0-100%) gradient on an isco flash chromatography system. The combined pure fractions were reduced in vacuo to yield the title compound as a yellow oil (3 g, 57.8%). MS: M+H=260. 1H NMR (DMSO-d6): delta 8.80 (s, 1H). 7.40-7.24 (m, 5H), 3.76 (s, 2H), 3.57 (s, 2H), 2.92 (t, 2H), 2.80 (t, 2H).

The mixture was concentrated in vacuo and the remaining black residue was taken up in dichloromethane (250 mL) and poured over ice. The mixture was carefully neutralized with the addition of solid sodium bicarbonate. The organic layer was separated and dried over sodium sulfate and concentrated in vacuo. The mixture was purified by silica gel column with EtOAc/hexane (0-100%) to yield the title compound as a yellow oil (3 g, 57.8%).
