Reaction Steps

A mixture of the product of Step B (0.07 g; 0.271 mmol) and Me3SiN3 (0.36 ml; 2.71 mmol) and 1M TBAF in THF (0.27 ml; 0.271 mmol) was stirred at 75±5° C. for 8 h in sealed flask. After cooling to room temperature, the mixture was diluted to 1 ml with MeOH, refluxed for 30 min under N2 and left overnight in refrigerator. The precipitate formed was filtered off, washed with Et2O and dried to give a title compound (0.069 g; 84%) as colourless solid. 1H-NMR (CD3OD) 7.32 (d, 2H, J=8.0 Hz); 7.21 (d, 2H, J=8.0 Hz); 4.72 (s, CD3OH); 4.34 (s, 2H); 4.16 (s, 2H); 2.59 (t, 2H, J=7.76 Hz); 1.57 (t, 2H, J=7.19 Hz); 1.25 (m, 10H); 0.84 (t, 3H, J=6.93 Hz);
