Reaction Conditions

Reaction Steps

Tetrabutylammonium fluoride 1 M in THF (12.2 ml, 42 mmol, 2.5 eq) was added to a solution of N-(4-(benzyloxy)pyridin-3-yl)-N-(methylsulfonyl)methane sulfonamide (6 g, 16.8 mmol, 1 eq) in THF at room temperature. The reaction mixture was refluxed at 60° C. for 10 h. The solution was concentrated completely and diluted with water (5 mL) and was allowed to stir for 15 minutes, The solid precipitated was filtered, washed with water and dried under vacuum yielding the expected product as a pale brown solid. 1HNMR (400 MHz, DMSO-d6): δ 335 (s, 3H), 5.27 (s, 2H), 7.21 (d, J=5.64 Hz, 1H), 7.36-7.54 (m, 3H), 7.54 d, J=7.28 Hz, 2H), 8.30 (s, 1H), 8.33 (d, J=5.64 Hz, 1H), 9.34 (s, 1H).
