Participants

Reaction Steps

Using methods substantially equivalent to Example 21-C, except that the Mitsonobu reaction was allowed to proceed for 7 to 10 days, methyl 2-(3-tert-butoxy-carbonylamino-2,2-dimethylpropoxy)-4-(tert-butyl)benzoate (10.85 g, 39%) as a pale yellow brittle foam was prepared from methyl 4-(tert-butyl)salicylate (14.72 g, 70.8 mmol) and 3-(tert-butoxycarbonylamino)-2,2-dimethylpropanol (14.37 g, 70.8 mmol).
