Methanesulfonyl chloride → 1-(2-chlorophenyl)-2-(4-methoxyphenyl)-5-(methylsulfonyl)-4,5,6,7-tetrahydro-1H-pyrrolo-[3,2-c]pyridine

Participants

Reaction Steps

To an 8-mL vial charged with piperidinomethyl polystyrene (3.57 mmol/g, 99.2 mg, 0.354 mmol) and a solution of 1-(2-chlorophenyl)-2-(4-methoxyphenyl)-4,5,6,7-tetrahydro-1H-pyrrolo[3,2-c]pyridine (Example 2), 40.0 mg, 0.118 mmol) in 4 mL dichloromethane was added methanesulfonyl chloride (18.2 μL, 0.236 mmol). The reaction mixture was mixed by orbital shaking for 4 h. The solid was removed by filtration. The filtrate was evaporated, and the residue was purified by preparative reversed-phase HPLC to give a solid (19.8 mg, 40%): Rf=0.20 (1:2 EtOAc/hexanes).
