実験手順: The title compound, white solid, m.p. 83° C. and MS: m/e=296.3 (M+H+) was prepared in accordance with the general method of example 39 from 2,2-diphenylacetamide and butanecarboxylic acid chloride.

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: The title compound, white solid, m.p. 87° C. and MS: m/e=309 (M+) was prepared in accordance with the general method of example 39 from 2,2-diphenylacetamide and pentanecarboxylic acid chloride.

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: The title compound, white solid, m.p. 205° C. and MS: m/e=281 (M+) was prepared in accordance with the general method of example 39 from 2,2-diphenylacetamide and propanecarboxylic acid chloride.

実験手順: To a stirred and cooled (0° C.) solution of 2,2-diphenylacetamide (500 mg, 2.36 mmol) in THF (20 ml) was added sodium hydride (95 mg, 2.36 mmol; 60%) and the mixture was stirred at RT for 0.5 h. Then cyclopropanecarboxylic acid chloride(247 mg, 2.36 mmol) dissolved in THF (5 ml) was added dropwise at RT and the solution was stirred at RT for 20 h. The reaction mixture was poured into sat. NaHCO3 solution (50 ml) and extracted with ethyl acetate (2×70 ml). The combined organic layers were washed with brine (50 ml), dried (MgSO4) and evaporated. Further purification by column chromatography (toluene/ethyl acetate 19:1) yielded the product which was recrystallized from ethyl acetate/hexane to give a white solid (133 mg, 20%), m.p. 178° C. and MS: m/e=279 (M+). the mixture was stirred at RT for 0.5 h was added dropwise at RT the solution was stirred at RT for 20 h extracted with ethyl acetate (2×70 ml) The combined organic layers were washed with brine (50 ml) dried (MgSO4) evaporated Further purification by column chromatography (toluene/ethyl acetate 19:1) yielded the product which was recrystallized from ethyl acetate/hexane
