Reaction Steps

The title compound was prepared as in Example 81 with 4-chlorophenylsulfonyl chloride replacing 2-naphthalenesulfonyl chloride and with 2-(1-methyl-pyrrolidin-2-yl)-ethylamine replacing 2-pyrrolidin-1-yl-ethylamine. The hydrochloride salt was prepared by treatment with hydrogen chloride in 1,4-dioxan. 1H NMR (DMSO-d6) 8-7 (1H, br s), 7.82-7.77 (2H, m), 7.50-7.46 (2H, m), 3.10-3.01 (3H, m), 2.39 (1H, m), 2.28 (3H, s), 2.15-2.12 (1H, m), 1.82-1.42 (6H, m). Microanalysis found C 51.65 H 6.44 N 8.99. C13H19ClN2O2S requires C 51.56 H 6.32 N 9.25.
