Yield:14770-51-5 77%

Reaction Conditions:

with deuteromethanol at 69;

Steps:

1

Synthesis of 2,2-d2-Propanoic-OD acid (21).; A solution of 2,2-d2-propanoic acid 20 (CDN, 98.5 atom% D, 15.00 g, 197 mmol) in methanol-di (Aldrich, 99.5 atom % D, 40 mL) was slowly distilled at atmospheric pressure until the distillate temperature exceeded 69 0C. Methanol-d] (40 mL) was added to the acid and distilled off three times to give 2,2-d2-propanoic-OD acid 21 (11.68 g, 77%). The complete hydrogen-to-deuterium exchange was verified by 1H NMR in the presence of triphenylmethane as standard.
