Reaction Steps

This example illustrates methods of converting the compounds of formula III into the compounds of formula II of the invention. In this example 1 g. of 5-(5-[2-(bicyclo[2.2.1]-hept-7-yl)ethylaminocarbonyl]thiazol-2-yloxy)methylene-N-t-butyl-2,2-dimethyloxazolidine is dissolved in 50 ml. of ethyl acetate and this solution is treated with aqueous 5% sodium hydroxide (20 ml.) at 20° C. The mixture is allowed to stand for 0.5 hours, washed three times with water, dried over magnesium sulfate and then evaporated to dryness affording 1-t-butyl-3-(5-[2-(bicyclo[2.2.1]hept-7-yl)ethylaminocarbonyl]thiazol-2-yloxy)-propan-2-ol.
