DIAD (23 mg, 0.116 mmol) was added to a solution of 3-amino-4-hydroxymethyl-6-methyl-thieno[2,3-b]pyridine-2-carboxylic acid amide (see Example 12) (25 mg, 0.105 mmol), 4-hydroxy-benzamide (15 mg, 0.116 mmol), and Ph3P (30 mg, 0.116 mmol) in THF (2.5 mL) at 0° C. The mixture was warmed to room temperature and stirred for 24 h. The reaction mixture was concentrated and triturated with 2:1 EtOAc:MeOH giving the title compound (7 mg, 19%) as an orange solid, m.p.>250° C.
