Participants

Reaction Steps

To a solution of {[(Z)-tert-butoxycarbonylimino]-trifluoromethanesulfonyl-methyl}-carbamic acid tert-butyl ester (13.62 g, 34.8 mM) and triethylamine (4.9 ml, 34.8 mM) in dry DCM (183 ml), 1-(4-aminophenyl)azetidin-3-ol (Method 37; 6.0 g, 36.5 mM) was added. The solution was stirred at room temperature under nitrogen for 48 hours. The reaction mixture was diluted with more DCM and washed with water (twice), saturated sodium bicarbonate solution (twice), water and saturated sodium chloride. The solution was then dried with anhydrous sodium sulphate, filtered and evaporated. The crude product was triturated with ether/isohexane (2:1), filtered washed with the same solvent and dried to give the title compound as a yellow solid (11.77 g, 83%). NMR 1.4 (s, 9H), 1.5 (s, 9H), 3.47 (t, 1H), 4.02 (t, 2H), 4.5 (m, 1H), 5.55 (d, 1H), 6.38 (d, 2H), 7.23 (d, 2H), 9.75 (s, 1H), 11.46 (m, 1H); m/z 407.
