(R)-3-(4-Hydroxy-phenylsulfanyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (3.0 g, 10.2 mmol) in CH2Cl2 (36 ml) was treated with trifluoroacetic acid (7.8 ml, 0.1 mol). After 1 hour stirring at room temperature, the reaction mixture was concentrated to provide (R)-4-(pyrrolidin-3-yl-sulfanyl)-phenol trifluoroacetic acid (3.46 g) as an orange oil, MS: m/e=196.2 (M+H+) and [α]D20=+25.060 ° (c=1.2, MeOH).
