A solution of the product from step b) (6.69 g, 20.4 mmol) was dissolved in EtOH (37 ml) and treated with 10% Pd/C (Wet Degussa type, 13.4 g) and heated to 40° C. for 2 days under H2 (1 atm). Next, the Pd/C was removed by filtration through celite, replaced with fresh 10% Pd/C (13.4 g) and the reaction was continued for two more days. The Pd/C was removed by filtration through celite and the EtOH was evaporated in vacuo to provide the subtitle compound (4.78 g, 71%). MS calculated for C19H23NO2S+H 330, observed 330.
