Procedure

To a solution of a 2-chlorobenzene sulfonyl chloride (10 g, 47.4 mmol) in DCM (100 ml) cooled to 0° C. was added pyridine (5.7 ml, 71.1 mmol) and morpholine (6.2 ml, 71.1 mmol) dropwise. Stirring was continued for 15 minutes after which time no sulfonyl chloride was evident by LC-MS. The reaction was quenched by the addition of 2N HCl, washed with further portions of 2N HCl, dried over sodium sulfate, filtered and concentrated in vacuo to yield the title compound without need for additional purification. (11.2 g, 100%). δH (400 MHz, DMSO-d6) 7.97 (1H, dd, 7.8, 1.5 Hz), 7.66-7.77 (2H, m), 7.58 (1H, ddd, 8.1, 6.7, 1.8 Hz), 3.57-3.64 (4H, m), 3.11-3.18 (4H, m); TR=1.25 min.
