YieldReaction ConditionsOperation in experiment
43% With oxyaziridine; In methanol; dichloromethane; at 20℃; EXAMPLE 52-MethanesuIfinyl-8H-pyrido[2,3-d]pyrimidin-7-one; To a suspension of <strong>[211244-81-4]2-methylsulfanyl-8H-pyrido[2,3-d]pyrimidin-7-one</strong> (WO 9833798 A2, 5.0 g, 25.9 mmol) in CH2Cl2 (100 mL), CHCl3 (50 mL) and MeOH (10 mL, the starting material still did not dissolve) was added the oxaziridine (8.11 g, 31.05 mmol, 1.2 equiv) as a solid. The reaction became homogenous after 3 h and was stirred overnight at RT. The reaction was concentrated and CH2Cl2ZMeOH was added to dissolve the residue. Much of the solid did not dissolve so the mixture was filtered to give 2-Methanesulfinyl-8H-pyrido[2,3-d]pyrimidin-7-one, as an off-white solid (2.31 g, 11.04 mmol, 43%). MS: APCI: M+l: 210.1 (Exact Mass: 209.03).

YieldReaction ConditionsOperation in experiment
64 mg (76% based on recovered starting material) In chloroform; ethyl acetate; Example 30 2-Methanesulfinyl-8H-pyrido[2,3-d]pyrimidin-7-one To a room temperature solution of <strong>[211244-81-4]2-methanesulfanyl-8H-pyrido[2,3-d]pyrimidin-7-one</strong> (120 mg, 0.62 mmol) in 20 mL of chloroform was added (+-)-trans-2-(phenylsulfonyl)-3-phenyloxaziridine (200 mg, 0.77 mmol). The solution was stirred at room temperature overnight. The solid was collected by filtration and found to be 2-methylthio-8H-pyrido[2,3-d]pyrimidin-7-one. The filtrate was stirred at room temperature for 2 days then concentrated. Addition of ethyl acetate resulted in the formation of a solid that was collected by filtration to provide 64 mg (76% based on recovered starting material) of 2-methanesulfinyl-8H-pyrido[2,3-d]pyrimidin-7-one, mp 237-242 C. Analysis calculated for C8H7N3O2S-0.2H2O: C, 45.15; H, 3.50; N, 19.74. Found: C, 45.41; H, 3.23; N, 19.80.
