Source of materials

In a 25 mL reaction vessel, a solution of propionaldehyde (10 mmol), ethyl 3-oxobutanoate (10 mmol), and 5-aminotetrazole (10 mmol) in 7.5 mL propane-1,2-diol and 2 mL water was sealed, and kept at 120 °C for 12 h before it was cooled to room temperature. The reaction solution was poured into 50 mL distilled water, stirred vigorously for 10 min, and then the solid of crude tetrazolopyrimidine was filtered out. Recrystallization with methanol and DMF gave the crystal product. IR (KBr, ν, cm−1) for C10H15N5O2: 3475, 3247, 3176, 3100, 2947, 2932, 1707, 1651, 1574, 1450, 1318, 1262, 1227, 1150, 1095, 1018, 990, 878, 844, 788, 672, 565, 472 [8]. 1H NMR (300 MHz, CDCl3) (δ, ppm) for C10H15N5O2: 11.08(s, 1H, NH), 5.82(s, 1H, CH), 4.26(s, 2H,CH2), 2.62(s, 3H, CH3), 2.08(s, 1H, CH2), 1.88(s, 1H, CH2), 1.34(s, 3H, CH3), 0.80(s, 3H, CH3) [9]. ESI–MS for C10H15N5O2[(M–1)−]: 236.46.

Experimental details

All the hydrogen atoms were calculated geometrically and with C–H distances ranging from 0.96 to 0.98 Å, with U iso(H) = 1.2–1.5U eq(C). N—H = 0.86 Å, with U iso(H) = 1.2U eq(N).

Comment

Tetrazolo[1,5-a]pyrimidines and their partially hydrogenated derivatives are very important chemical intermediates [6]. To address green chemistry principles for the synthesis of dihydro tetrazolo pyrimidines, one may concern carrying out these reactions under solvothermal conditions with propane-1,2-diol and water as mixture solvents [7].

There is one crystallographically independent molecule in the asymmetric unit. Almost all non-hydrogen atoms are coplanar except C(6) and C(7) from propionaldehyde [10]. Distance between N1–C2 (1.393 Å) is shorter than C5–N2 (1.473 Å). The tetrazole conjugated system extends to C3 from N1. The pyrimidine ring is in a flattened boat conformation [11]. Two adjacent molecules are connected by N(1)—H···N(2) intermolecular hydrogen bonds. Bond lengths and angles are as expected [].
