Reaction Steps

To a solution of 19.59 g (108 mmol) of ethyl N-(4-methoxyphenyl)glycine in 100 mL of THF under N2 was added 5.44 g (130 mmol) of lithium hydroxide monohydrate in 25 mL water. After 15 hours, the mixture was reduced to ½ the original volume in vacuo and then acidified with concentrated hydrochloric acid to ph 3 and a precipitate formed. The solid was collected and washed with 100 mL water, then dried in vacuo to give 9.92 g (51%) of the desired compound as a off-white solid. 1H NMR (CDCl3): δ 6.68 (d, J=8.8, 2H); 6.49 (d, J=8.8, 2H); 3.73 (s, 2H); 3.64 (s, 3H); 2.49 (br s, 2H).
