Vorschrift

A solution of 4-(1-methylcyclobutyl)-2-nitroaniline (138 mg. 0.668 mmol) in ethanol (8.5 mL, 140 mmol) was carefully treated with 10% Palladium on Carbon (14.2 mg, 0.0134 mmol) as a slurry in ethanol. The reaction flask was evacuated and filled with hydrogen gas three times and the reaction mixture was stirred under an atmosphere of Hydrogen for 4 h. The reaction mixture was filtered through a pad of Solka floc® and the pad was washed with 20 ml MeOH. The filtrate was concentrated to yield an oil which was placed under high vacuum yielding the desired compound as a solid (119 mg) which was used directly in the next step. 1H NMR (400 MHZ.
