Procedure

A solution of 7,7-dimethyl-5-(2-nitrophenylsulfonyl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine-2-carboxylic acid (20 g, 50 mmol) was cooled to 0° C. DIPEA (32.3 g, 250 mmol) was added and the solution was stirred at 0° C. for 30 minutes. O-(tetrahydro-2H-pyran-2-yl)hydroxylamine (5.8 g, 50 mmol) and HATU (22.8 g, 60 mmol) were then added and the reaction was allowed to warm to room temperature overnight. The reaction mixture was washed with water, brine and dried over anhydrous Na2SO4, concentrated and purified by silica gel chromatography (20-50% EtOAc/hexane) to afford product (23.5 g, 94%). LCMS (FA) ES+ 496; 1H NMR (400 MHz, DMSO) δ 11.60 (s, 1H), 8.10 (dd, J=7.7, 1.5 Hz, 1H), 8.02 (dd, J=7.7, 1.5 Hz, 1H), 7.90 (dtd, J=17.6, 7.5, 1.4 Hz, 2H), 7.41 (s, 1H), 4.92 (s, 1H), 4.33 (s, 2H), 4.00 (s, 1H), 3.50 (d, J=11.1 Hz, 1H), 3.38 (s, 2H), 1.72 (d, J=22.2 Hz, 3H), 1.53 (s, 3H), 1.27 (s, 6H).
