Methyl 6-chloro-5-nitronicotinate → HCID 22145708, compound

Participants

Reaction Steps

Sodium thiomethoxide (9.1 g) in dry methanol (50 mL) is added dropwise to a stirred solution of methyl 6-chloro-5-nitronicotinate (25.1 g) in dry methanol (400 mL) and the mixture stirred for 4 hours. The pasty mixture is evaporated to low volume, diluted with water and the product extracted into ethyl acetate. The extracts are washed with water and brine, and finally dried (MgSO4). Evaporation gave methyl 6-methylthio-5-nitronicotinate (16.8 g) as a yellow solid. The solid can be recrystallised from cyclohexane to give a yellow solid m.p. 115-6° C.
