Procedure
In the same manner, ethyl N-{2-(4-hydroxyphenoxy]ethyl}carbamate (1.25 g, 5.5 mmol) and sodium hydride, prewashed with pentane, (0.132 g, 5.5 mmol) are reacted together, followed by addition of 1-methylbutyl bromide. The mixture is heated at 50° for 20 hours, then worked up and purified by prep. TLC to give ethyl N-{2-[4-(1-methylbutoxy)phenoxy]ethyl}carbamate (compound 14, Table A).
