Participants

Reaction Steps

To a solution of 4-methyl-5-naphthalen-1-yl-thiazole-2-carboxylic acid in methylene chloride (2 ml) is added BOP (44 mg, 0.10 mmol), isopropylpiperazine (13 mg, 0.10 mmol) and Et3N (20 mg, 0.20 mmol). The reaction mixture is stirred at rt for 2 hr. Solvent is removed and the resulting mixture is purified by PTLC to give the title compound. LC-MS M+1 380.03. 1H NMR δ (CDCl3) 7.90-7.96 (m, 2H), 7.68-7.72 (m, 1H), 7.46-7.56 (m, 4H), 4.51 (brs, 2H), 3.85 (brs, 2H), 2.77 (m, 1H), 2.67 (brs, 4H), 2.25 (s, 3H), 1.10 (d, 6H). LC-MS (M+1) 380.1.
