Procedure
To a solution of the isocyanate from Step 1 in toluene was added 1.2 equivalent of isopropylamine. The reaction mixture was kept under reflux for 1 h. After having been cooled to room temperature, the mixture was diluted with n-hexane to form a yellow precipitate, which was filtered off, and was recrystallized from CH2Cl2, to give the title compound as a yellow solid (750%), mp: 217° C.
