Reaction Conditions:
with sodium hydroxide in methanol;water at 70;
Steps:
9.3 Synthesis of 2-[2-(methylsulfanyl)pyrimidin-4-yl]-3-oxopropanenitrile
Into a 25-mL round-bottom flask, was placed a solution of 2-(methylsulfanyl)-4-(1,2-oxazol-4-yl)pyrimidine (1.0 g, 5.18 mmol, 1.00 equiv) in methanol/water (5/5 mL).
Sodium hydroxide (210.0 mg, 5.25 mmol, 1.00 equiv) was added.
The resulting solution was stirred overnight at 70° C. in an oil bath.
The resulting mixture was concentrated under vacuum.
The pH value of the solution was adjusted to 3-4 with hydrogen chloride.
The solids were collected by filtration, concentrated under vacuum.
This resulted in 1.0 g (100%) of 2-[2-(methylsulfanyl)pyrimidin-4-yl]-3-oxopropanenitrile as a brown solid.
LC-MS (ES+): m/z 193.85[MH+], tR=0.48 min, (1.9 minute run).
