To a solution of 5-bromo-6-(3-methyl-oxetan-3-ylmethoxy)-pyridine-2-carboxylic acid (Example 280b) (30 mg, 100 μmol) in dry DMF (1 ml) was added 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (29.1 mg, 105 μmol) and Hunig's base (52.4 uL, 300 umol). The reaction was stirred at r.t for 30 min, followed by addition of α,α-Dimethyl-2-thiazolemethanamine (Example 12c) (14.2 mg, 100 μmol). The reactions was stirred at room temperature overnight and monitored by LC-MS. When the reaction was complete, purification was directly done by preparative HPLC without any work-up procedure to give the title compound (9.8 mg, 23%). MS (EI): m/e=425.9 [M+H]+.
