実験手順: A solution of ethyl 2-(4-aminophenyl)-2-methylpropanoate (30 mg, 0.145 mmol) in THF (1 mL) was treated with LiAlH4 (1M solution in THF, 0.226 mL, 0.226 mmol) at 0° C. and stirred for 15 min. The reaction was treated with 0.1N NaOH, extracted with EtOAc and the organic layers were dried over Na2SO4. The solvent was removed under reduced pressure to yield 2-(4-aminophenyl)-2-methylpropan-1-ol (G-2), which was used without further purification: 1H NMR (400 MHz, CDCl3) δ 7.17 (d, J=8.5 Hz, 2H), 6.67 (d, J=8.5 Hz, 2H), 3.53 (s, 2H), 1.28 (s, 6H). extracted with EtOAc the organic layers were dried over Na2SO4 The solvent was removed under reduced pressure

実験手順: The product from Example 194B (0.321 g, 1.644 mmole) was dissolved in a mixture of THF (10 mL) and ethanol (2 mL). To this was added platinum(IV) oxide (0.030 g, 0.131 mmole). The flask was capped with a septum and the contents vacuum degassed three times. Hydrogen was introduced via a balloon and the mixture stirred at room temperature. An additional 38.2 mg (0.167 mmole) of catalyst was added in two aliquots before chromatographic analysis indicated that the starting material was consumed. After stirring overnight under hydrogen the mixture was filtered through a sand/celite plug followed by an ethyl acetate rinse. The filtrate was concentrated to dryness and the residue purified by chromatography on amine modified silica gel eluting with ethyl acetate—hexane beginning at 8% and advancing to 66% ethyl acetate to provide the title compound (0.3645 g, 68% yield) as a clear oil. MS (DCI+) m/z @ 183.1 (M+NH4)+. The flask was capped with a septum the contents vacuum degassed three times Hydrogen was introduced via a balloon was consumed After stirring overnight under hydrogen the mixture was filtered through a sand/celite plug rinse The filtrate was concentrated to dryness the residue purified by chromatography on amine
