Reaction Steps

Methyl 2-chloro-4-(1-methyl-1H-1,2,4-triazol-5-yl)-1,3-thiazole-5-carboxylate (Intermediate 2, 77.91 mg, 3.02 mmol) was added to a solution of 3,4-dichloro-5-methyl-N-[(3S,4R)-3-(prop-2-en-1-yloxy)piperidin-4-yl]-1H-pyrrole-2-carboxamide (Intermediate 20, 100 mg, 3.02 mmol) and N,N-diisopropylethylamine (0.362 mL, 0.06 mM) in N-methyl 2-pyrrolidinone (1.5 mL) and the resulting reaction mixture was stirred overnight at 80° C. The reaction mixture was cooled to room temperature and poured into water (20 mL). The solid that formed was collected by filtration, washed with diethylether (25 mL) and dried to afford Methyl 2-[(3S,4R)-4-{[(3,4-dichloro-5-methyl-1H-pyrrol-2-yl)carbonyl]amino}-3-(prop-2-en-1-yloxy)piperidin-1-yl]-4-(1-methyl-1H-1,2,4-triazol-5-yl)-1,3-thiazole-5-carboxylate (90 mg, 70%) as solid.
