Reaction Conditions

Temperature130 °C

Reaction Steps

100 mg (0.238 mmol) of the amine (Example 8A) are introduced into 3 ml of DMSO, 76 mg (0.357 mmol) of 2-bromo-5-nitro-1,3-thiazole and 154 mg (1.19 mmol) of DIEA are added, and the mixture is heated in a microwave at 130° C. for 30 min. Purification by preparative HPLC results in 35 mg (33% of theory) of the product as a solid.
