Procedure
Sodium azide (390 mg, 6.0 mmol) was added to a DMSO (5 mL) solution of Intermediate 4: 1-(4-(chloro-methyl)thiazol-2-yl)-3-(3-fluorobenzyl)urea (600 mg, 2 mmol). The mixture was stirred for 4 hours at 40 C. Upon completion of the reaction, water was added at 10 C and the mixture was extracted with EtOAc. Organics were washed with brine, dried and evaporated. Recrystallization from CH2Cl2/hexane afforded 1-(4-(azidomethyl)thiazol-2-yl)-3-(3-fluorobenzyl)urea. 1H NMR (400 MHz, CDCl3): δ 10.3 (1H, br), 7.27 (m, 1H), 7.1-6.9 (m, 3H), 6.74 (s, 1H), 4.50 (d, 2H), 4.27 (s, 2H). MS (ES+): M/Z 307 (M+H)+.
