Participants

Reaction Steps

To a mixture of 1-[2-(2-chloropyridin-4-yl)thiazol-4-yl]-3-(6-morpholin-4-ylmethyl-pyridin-2-yl)urea (100 mg, 0.23 mmol, Example 90) and EtOH (50 mL) was added a 21 wt % NaOEt/EtOH solution (0.4 mL, 1.2 mmol) and DMF (2 mL). The mixture was heated to reflux for 15 h then additional 21 wt % NaOEt/EtOH solution (10 mL) were added. After 2.5 h, the reaction was complete as judged by LC/MS. The reaction mixture was concentrated in vacuo then diluted with EtOAc and the solid was filtered off. The filtrate was concentrated in vacuo to afford an orange slushy oil which was purified by silica flash chromatography (5–10% MeOH/CH2Cl2) to afford the title compound as a yellow solid. MS m/z: 441.1 (M+H). Calc'd for C21H24N6O3S: 440.16.
