Procedure

A CH2Cl2 (5 mL) suspension of 1-(4-(chloromethyl)thiazol-2-yl)-3-(3-fluorobenzyl)urea (Intermediate XXI) (90 mg, 0.30 mmol), N,3-dimethylpyrazin-2-amine (69 mg, 0.56 mmol) and finely powdered K2CO3 (83 mg, 0.60 mmol) was evaporated to dryness. This mix was heated at 80° C. for 60 hours. Upon cooling, the organics were taken up in CH2Cl2 (3×5 mL) and the insolubles were removed by filtration. The volatiles were then removed in vacuo. The crude product was purified with chromatography (silica 1-4% MeOH in CH2Cl2) to afford the title compound. 1H NMR (400 MHz, CDCl3): 8.00 (s, 2H), 7.23 (m, 1H), 6.95 (m, 3H), 6.60 (s, 1H), 4.45 (d, 2H), 4.37 (s, 2H), 2.87 (s, 3H), 2.52 (s, 3H). MS (ES+): M/Z 387 (M+1).
