Methanesulfonyl chloride → N-(1-methylcyclopentyl)methanesulfonamide

Participants

Reaction Steps

To a stirred solution of 1-amino-1-methylcyclopentane hydrochloride (0.165 g, 1.2 mmol) in pyridine (1 mL) was added methanesulfonyl chloride (0.169 mL, 2.2 mmol). The reaction mixture was stirred at room temperature for 16 hrs and then concentrated. The mixture was diluted with ethyl acetate and washed with 1 N aqueous hydrochloric acid, saturated aqueous sodium bicarbonate, saturated aqueous sodium chloride, dried (anhydrous sodium sulfate), filtered, and concentrated to afford the product as a brown oil (0.100 g, 46%). 1H NMR (300 MHz, CDCl3) δ 4.27 (br s, 1H), 3.04 (s, 3H), 2.00-1.60 (m, 8H), 1.50 (s, 3H).
