Procedure: 4-(4-Nitro-benzyl)-thiomorpholine 1,1-dioxide (110 mg, 0.41 mmol) is dissolved in MeOH (7 mL). To this solution is added FeCl3.6H2O (−20 mg, 0.07 mmol) and active Charcoal (12 mg, 1.0 mmol). The suspension is heated to reflux. Hydrazine hydrate (0.5 mL) is added, and reflux is continued for 4 h until full conversion, the active Charcoal is filtered off through Celite, and the MeOH is removed under reduced pressure. The residue (85 mg, 86%) is directly used in the next step. The suspension is heated to reflux reflux the active Charcoal is filtered off through Celite the MeOH is removed under reduced pressure

The mixture was then diluted with water (30 ml) and the resulting solid collected by filtration and dried (882 mg) the resulting solid collected by filtration dried (882 mg)

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 5′-cyano-2′-methyl-biphenyl-4-carboxylic acid (100 mg), 4-(1,1-dioxo-1lambda*6*-thiomorpholin-4-ylmethyl)-phenylamine (101 mg), EDAC (81 mg), HOBT (57 mg) and N-methylmorpholine (0.09 ml) in dry DMF (2 ml) was stirred at 20 C for 18 h. Water (8 ml) was then added and the resulting solid collected by filtration and dried (160 mg). the resulting solid collected by filtration dried (160 mg)

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 5′-(cyclohexanecarbonyl-amino)-2′-chloro-biphenyl-4-carboxylic acid (100 mg), 4-(1,1-dioxo-1lambda*6*-thiomorpholin-4-ylmethyl)-phenylamine (67 mg), triethylamine (0.098 ml) and HBTU (159 mg) in dry DMF (5 ml) was stirred at 20 C for 18 h. The mixture was then evaporated to dryness and purified via reversed-phase preparative HPLC (eluting with acetonitrile/water) to afford the title compound as an orange solid (35 mg). The mixture was then evaporated to dryness purified via reversed-phase preparative HPLC (eluting with acetonitrile/water)
