Procedure

A glass microwave reaction vessel was charged with N-isopropyl-5-(3-(6-((4-methoxybenzyl)oxy)-2-(methylsulfonyl)pyrimidin-4-yl)-1-tosyl-1H-indol-5-yl)-1,3,4-oxadiazol-2-amine (120 mg, 0.174 mmol) and isopropylamine (0.075 mL, 0.871 mmol) in NMP (1.0 mL). The reaction mixture was stirred and heated in an Initiator microwave reactor (Personal Chemistry, Biotage AB, Inc., Upssala, Sweden) at 120° C. for 1 h. The mixture was diluted with water and filtered. The remaining solid was dried to give the crude product (100 mg), which was used in the next step without further purification. MS (ESI, pos. ion) m/z: 668.0 (M+1).
