Reaction Steps

A mixture of 6-chloro-4-((1S,2S)-2,3-dihydroxy-1-phenylpropylamino)nicotinonitrile (0.108 g, 0.356 mmol), benzo[d]thiazol-6-amine (0.187 g, 1.244 mmol) and NMP (1.422 mL) was stirred at 150° C. for 1 hour in a microwave reactor. The vessel was cooled to room temperature, diluted with water and filtered. Following drying on a buchner funnel, 6-(benzo[d]thiazol-6-ylamino)-4-((1S,2S)-2,3-dihydroxy-1-phenylpropylamino)nicotinonitrile (0.122 g, 0.292 mmol, 82% yield) was collected as a yellowish solid. LC-MS (m/z, M+1=418), Waters sunfire 4.6×50 mm C18 5 um 4 min/1 min hold time 0-100% (A-B) A=10% MeOH-90% water-0.1% TFA, B=90% MeOH-10% water-0.1% TFA RT=2.06.
