Reaction Steps

(RS)-4-[1-(Toluene-4-sulfonyl)-pyrrolidin-3-ylsulfanyl]-phenol (1.9 g, 5.44 mmol) in phenol (5.1 g, 54.4 mmol) was treated with HBr (25 ml, 48%). After 4 hours stirring at 100° C., the reaction mixture was cooled to room temperature and quenched with H2O and CH2Cl2. The aqueous phase was washed with CH2Cl2 and concentrated to provide (RS)-4-(pyrrolidin-3-ylsulfanyl)-phenol hydrobromide (1.13 g, 75%) as a brown oil, MS: m/e=196.2 (M+H+). Following the general method of example 74, the compounds of example 75 to example 77 were prepared.
