Participants

Reaction Steps

To the product from Example 15D (2.12 g, 3.30 mmol) in a 250 ml round bottom flask was added acetonitrile (40 ml) and 0.1% trifluoroacetic acid in water (40 ml) and the reaction was stirred at room temperature for 4 days. Every 24 hours 0.5 ml of trifluoroacetic acid was added until day four. The reaction was concentrated to give a white powder in 81% yield. 1H NMR (CDCl3, 300 MHz); δ ppm 1.32 (s, 9H), 1.88-1.92 (m, 1H), 2.22-2.26 (m, 2H), 2.57-2.63 (m, 1H), 2.84-2.90 (m, 1H), 2.96-3.32 (m, 1H), 4.21 (m, 2H), 4.65 (t, J=6.11, 12.55Hz, 2H), 5.29 (t, J=7.46, 14.58 Hz, 1H), 7.28-7.31 (m, 3H), 7.52 (t, J=8.14, 16.28 Hz, 1H), 7.73 (d, J=7.45Hz, 1H), 7.83 (d, J=8.48Hz, 1H), 8.36 (s, 1H); MS (DCI/NH3) m/z 531.00; Calc for C25H31N4O7P: C, 54.45; H, 5.59; N, 9.92. Found: C, 54.84; H, 5.88; N, 9.92.
