A microwave vial was charged with 5-(2-(1-methyl-1H-pyrazol-5-yl)-4-(trifluoromethyl)phenyl)-1,2,3,4-tetrahydroisoquinoline (Intermediate O, 55.90 mg, 0.156 mmol), 2-oxo-N-(pyrimidin-2-yl)oxazolidine-3-sulfonamide (Intermediate Q, 96 mg, 0.391 mmol), and acetonitrile (587 μl) to give a suspension. Triethylamine (218 μl, 1.564 mmol) was added resulting in the formation of a yellow solution. The vial was sealed and heated in a microwave reactor for 30 min at 130° C. The mixture was concentrated, then chromatographed on a 12 g silica gel column with 0 to 10% MeOH/DCM to provide 5-(2-(1-methyl-1H-pyrazol-5-yl)-4-(trifluoromethyl)phenyl)-N-(pyrimidin-2-yl)-3,4-dihydroisoquinoline-2(1H)-sulfonamide (33.42 mg, 0.065 mmol) as a light-yellow solid.
