2-Phenylpropionic acid → Methyl alpha-methylbenzeneacetate

Participants

Reaction Steps

Trimethylsilyl diazomethane (2.0M in hexanes, 40 mL, 80 mmol) was added dropwise to a solution of racemic 2-phenylpropionic acid (10.0 g, 66.6 mmol) in benzene (100 mL) and methanol (20 mL) cooled in an ice bath. After the addition was complete the reaction solution was stirred at room temperature for 2 hours. The solution was then concentrated to give the indicated product. m/z=165.1 (M+H).
