Versuchsvorschrift
A mixture of 2-amino-1-diphenylmethoxy-2-methylpropane (7.6 g -- see Preparation 1) and ethyl formate (6.7 g) was heated at 100° in a steel bomb for 18 hours and evaporated. The residue was purified by chromatography on silica (18 g) using hexane plus 0-100% methylene chloride as the eluant. Appropriate fractions were combined and evaporated to give the title compound as a colourless gum (8.4 g, 99%).
