Procedure

By the method of Exaple 7, N-(2-Amino-4,6-dichloro-5-pyrimidinyl)formamide (Example 3, 2.56 g, 52.4 mmol) was reacted with (4R)-4-amino-1-cyclopentene-1-methanol (1.4 g, 52.4 mmol), available from (-)-2-azabicyclo[2.2]hept-5-en-3one (Chiroscience) by methods described in Examples 1-4 and 42 of U.S. Pat. No. 5,049,671. Crystallization from ethyl acetate--methanol gave title compound as white crystals, m.p. 148-150° C.; mass spectrum (CI/CH4): 286, 284 (M+1), 190, 188 (B+M); 1H-NMR (DMSO-d6)δ: 8.97 and 8.55 (s and d with J=11.3 Hz, total 1, NHCHO), 8.12 and 7.80 (s and d with J=11.5 Hz, total 1, CHO), 7.00 and 7.78 (both d, J=7.4 Hz, total 1, NH), 6.60 and 6.40 (both 8, total 2, NH2), 5.48 (s, 1, =CH), 4.74 (t, J=5.5 Hz, 1, OH), 4.74-4.60 (m, 1, NCH), 4.0-3.90 (m, 2, CH2O), 2.75-2.55 and 2.40-2.15 (both m, 2 each, 2CH2); [α]58920 -4.4°, [60 ]57820 -5.2°, [α]54620 -4.8°, [α]43620 -20.0°, [α]36520 -60.4°, (c 0.25, methanol).
