Procedure

(1R,2S)-1-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-1-(1-(4-fluorophenyl)-1H-indazol-5-yloxy)propan-2-amine (43a, 102 mg, 0.24 mmol) and DIPEA (170 μL, 0.97 mmol) was dissolved in NMP (2 mL). cyclopropanesulfonyl chloride (40 μL, 0.39 mmol) was added and the reaction mixture was stirred at room temperature for 1 hour. The reaction mixture was diluted with water (10 mL) and extracted with EtOAc (2×10 mL), the organic phase was washed with brine, dried (Na2SO4), filtered and evaporated to give an oily residue (NMP residues). The crude material was further purified by HPLC. Yield 80 mg (62%)
