Procedure

Title compound was prepared by a method analogous to that described for Intermediate 41, replacing the benzyl halide by 4-(chloromethyl)-2-methyl-1,3-thiazole hydrochloride (MAYBRIDGE). 4-(chloromethyl)-2-methyl-1,3-thiazole hydrochloride (MAYBRIDGE) was also liberated using NaOH (1N, aq) at room temperature. 1H NMR (300 MHz, DMSO-d6) δ ppm: 10.37 (s, 1H), 7.62-7.63 (m, 1H), 7.25 (s, 1H), 6.43-6.44 (m, 1H), 5.20 (s, 2H), 2.59 (s, 3H), 1.93 (s, 3H). [ES+MS] m/z 237 (MH+).
