20 Etapa 4
Se añadieron acetato de paladio (II) (2,5 mg, 0,011 mmol) y trifenilfosfina (11 mg, 0,044 mmol) a diisopropilamina (4 mL), y la mezcla se agitó a temperatura ambiente durante 20 min. Se añadieron N-(4-bromofenil)acetamida (78 mg, 0,365 mmol) y 2-[(4-etinilfenil)acetil]hidrazinacarboxilato de terc-butilo (100 mg, 0,365 mmol), y la mezcla se agitó a
25 70°C durante 2 h. Se añadió acetonitrilo anhidro (2 mL), y la mezcla se agitó adicionalmente a 70°C durante 1 h. La mezcla de reacción se enfrió y se concentró. El residuo se purificó por cromatografía en columna de gel de sílice (diclorometano:metanol = 97:3) para dar 2-({4-[(4-acetamidofenil)etinil]fenil}acetil)hidrazinacarboxilato de terc-butilo (30 mg, rendimiento 20%).
