Reaction Steps
To a stirred solution of (4-hydroxy-2-methoxy-benzyl)-carbamic acid tert-butyl ester (22.8 mg, 0.09 mmol) in 2-propanol (1 mL) and 2 N aq. NaOH (0.15 mL) is added 2-bromoethanol (22.5 mg, 0.18 mmol). The reaction mixture is heated to 85° C. and stirred for 8 h. The mixture is cooled to rt and subjected to prep. HPLC purification to give [4-(2-hydroxy-ethoxy)-2-methoxy-benzyl]-carbamic acid tert-butyl ester (10.3 mg) as a colourless oil. LC-MS: tR=0.85 min, [M+1]+=298.07.
