(Trimethylsilyl)diazomethane (2.0 M) solution in hexanes (1 mL, 2 mmol) was added to a solution of 5.4 (0.34 g, 2 mmol) in 15 mL of methanol:dichloromethane (3:7). The solvents were removed under reduced pressure resulting in 100% conversion of starting material to product. 1H NMR (300 MHz, CDCl3) δ2.24 (dt, J=3.66, 12.1 Hz, 1H), 2.10 (dd, J=2.7, 6.5 Hz, 2H), 2.06 (dd, J=1.54, 6.54 Hz, 1H), 2.00-1.89 (m, 3H), 1.76 (d, J=2.3 Hz, 1H), 1.43 (dq, J=3.28, 13.1 Hz, 2H), 1.03 (dq, J=3.28, 13.1 Hz, 2H). 13C NMR (300 MHz, CDCl3) δ176.8, 83.3, 69.8, 51.9, 43.4, 36.7, 31.9, 29.2, 26.3.
