Procedure

To an ice cooled solution of 5-bromo-2-(3-(ethoxycarbonyl)-5-methyl-1H-pyrazol-1-yl)benzoic acid (45.0 g, 127.8 mmol) in DCM (450 mL) were added (S)-(1,2,3,4-tetrahydroisoquinolin-3-yl)methanol (20.8 g, 102.27 mmol), HATU (72.7 g, 191.2 mmol), DIPEA (55.7 mL, 319.6 mmol) followed by stirring at RT for 12 h. The reaction mixture was diluted with DCM (750 mL), washed with water (500 mL), brine (100 mL), dried over sodium sulphate and concentrated invacuo. The residue was purified on silica gel (100-200 mesh) to afford the the title compound as a liquid 50 g (79%). Rf=0.44 (55% EtOAc in hexane); 1H NMR (400 MHz, DMSO-d6): δ 8.00-7.40 (m, 3H), 7.30-7.00 (m, 4H), 6.80-6.40 (m, 1H), 5.10-3.80 (m, 7H), 3.50-2.40 (m, 3H), 2.40-2.10 (m, 3H), 1.30-1.00 (m, 3H); ES-MS: m/z 498.2 (M+H).
