Procedure

A solution of 2,4-dichloronitrobenzene (VII, 20.0 g) and 2-amino-2-methyl-1-propanol (VIII, 80 ml) is stirred at 110° for 68 hr. After cooling to 20°-25°, adding water, extracting with methylene chloride, separating the phases and drying the organic phase over magnesium sulfate) gives the desired product sufficiently pure (>90%) to be carried on without further purification. An analytical sample is prepared by recrystallization from ethyl acetate/hexane to give the title compound, mp 102°-104°; IR (mineral oil) 3335, 2954, 2925, 1610, 1577, 1492, 1467, 1331, 1251, 1154 and 748 cm-1 ; NMR (CDCl3) 8.55, 8.13, 7.09, 6.59, 3.71, 2.11 and 1.48 δ; MS (m/z) 244, 213 and 166.
