Yield:-
Reaction Conditions:
in formic acid at 20; for 4 h;Cooling with ice;
Steps:
1.a Step a) Preparation of N-Formyl-D-Methionine
Step a) Preparation of N-Formyl-D-Methionine
D-Methionine (3g, 200mmol) was added into a solution of 1 1 ml_ of acetic anhydride and 4.5 ml_ of formic acid cooled in an ice-water bath. The mixture was stirred at room temperature for 4 hours, then the reaction solution was quenched with methanol and concentrated to provide the product which was used in the next step without purification.
