Participants

Reaction Steps

To a suspension of K2CO3 (24 mg, 0.17 mmol) in H2O (0.2 mL) and MeOH (1 mL) was added a solution of 4-benzyl-1,4-dihydropyrrolo[3,2-b]pyrrole-2-carboxylic acid 13 (82 mg, 0.34 mmol) in MeOH (2 mL). The solution was stirred for 35 min and then concentrated in vacuo to give potassium 4-benzyl-1,4-dihydro-pyrrolo[3,2-b]pyrrole-2-carboxylate 13a as a grey solid (93 mg, 98%). 1H NMR (400 MHz, (CD3)2SO) δ (ppm) 9.61 (s, 1H) 7.27-7.33 (m, 2H) 7.19-7.26 (m, 3H) 6.74 (d, J=2.9 Hz, 1H) 5.90 (s, 1H) 5.73 (dd, J=2.9, 0.8 Hz, 1H) 5.04 (s, 2H).
