Application
TCI Practical Example: Methyl Esterification of Carboxylic Acid Using TMS Diazomethane
-
Used Chemicals
-
- Boc-D-Ser(Bzl)-OH [B1863]
- Trimethylsilyldiazomethane (ca. 10% in Hexane, ca. 0.6mol/L) [T1146]
- Diethyl ether
- Methanol
-
Procedure
-
To a stirred solution of Boc-D-Ser(Bzl)-OH (596 mg, 2.02 mmol) in Et2O/MeOH (7:2, 18 mL) was added TMS-diazomethane (0.6 mol/L hexane solution, 4.0 mL, 2.4 mmol) dropwise for 5 min at 0 °C and the mixture was stirred at the same temperature. After 2 h, TMS-diazomethane (0.4 mL, 0.24 mmol) was added and stirred for further 3 h. The reaction mixture was allowed to warm to room temperature and concentrated in vacuo to give Boc-D-Ser(Bzl)-OMe (625 mg, 100%) as a pale brown oil.
-
Experimenter’s Comments
-
The reaction mixture was monitored by TLC (ethyl acetate:hexane = 3:1, Rf = 0.52).
Nitrogen gas evolution was observed when TMS-diazomethane was added dropwise.

Application
Safe Methyl Esterification Reagent
Typical Procedure: To a solution of fatty acid (0.10 mmol) in 20% methanolic benzene (1 mL) is added trimethylsilyldiazomethane (ca. 10% in hexane) (0.5 mL) and stirred. The mixture is left for 30 min at room temperature and used for a GC sample.
