Versuchsvorschrift

To a solution of hemi-aminal A1 from Example 1 (4 g, 8.4 mmol), 4-dimethylaminopyridine (0.15 g, 1.3 mmol) and triethylamine (1.1 mL, 7.5 mmol) in dichloromethane (30 mL) was added benzylisocyanate (1.03 mL, 8.3 mmol) and the reaction mixture stirred for 24 hours. The reaction mixture was then heated at 35° C. for 20 hours, cooled and washed with water/brine (1:1, 50 mL). The organic phase was dried over MgSO4, filtered and evaporated under vacuum. The residue was further purified by chromatography on silica eluting with ethyl acetate/dichloromethane/methanol (1:1:0.1) to give the desired product as an off white foam (530 mg, 14% yield). 1H NMR (CDCl3, 300 MHz) δ 1.58-1.88 (m, 4H), 2.48 (t, 2H), 2.60-2.72 (m, 6H), 2.85 (m, 2H), 300-3.12 (m, 4H), 3.96 (t, 2H), 4.40 (d, 2H), 5.13 (NH), 5.96 (s, 2H), 6.58 (dd, 1H), 6.79 (d, 1H), 6.92-6.98 (m, 1H), 7.04 (d, 1H), 7.12-7.16 (m, 1H), 7.23-7.35 (m, 6H); m/z (M+H) 611.12 and 613.10.
