Reaction Steps
The product of step b) (57.8 mg, 0.183 mmol) in MeOH (51 μl) was treated with CuO (7 mg, 0.09 mmol), a 25% solution of sodium methoxide in MeOH (129 μl) and tetra-butylammonium iodide (TBAI) (10 mg) at 100° C. for 12 hours. The reaction mixture was cooled and purified by preparative LC/MS to give the title compound. 1H NMR (300 MHz, CDCl3, ppm) 2.40-2.60 (m, 1H); 2.82-3.01 (m, 2H); 3.05-3.63 (br m, 4H); 3.77 (s, 3H); 3.81-3.98 (br s, 1H); 6.17 (s, 1H); MS calculated for C10H13NOS+H 196, observed 196.
